The main purpose of Apache Spark is offering an integrated platform for big data processes. It also offers robust APIs in Python, Java, R and Scala. Additionally, integration with Hadoop ecosystem is very convenient.

Why Apache Spark for ML applications?

Many machine learning processes involve heavy computation. Distributing such processes through Apache Spark is the fastest, simplest and most efficient approach. For the needs of industrial applications, a powerful engine capable of processing data in real time, performing in batch mode and in-memory processing is vital. With Apache Spark, real-time streaming, graph processing, interactive processing and batch processing are possible through a speedy and simple interface. This is why Spark is so popular in ML applications.

Apache Spark Use Cases:

Below are some noteworthy applications of Apache Spark engine across different fields:

Entertainment: In the gaming industry, Apache Spark is used to discover patterns from the firehose of real-time gaming information and come up with swift responses in no time. Jobs like targeted advertising, player retention and auto-adjustment of complexity levels can be deployed to Spark engine.

E-commerce: In the ecommerce sector, providing recommendations in tandem with fresh trends and demands is crucial. This can be achieved because real-time data is relayed to streaming clustering algorithms such as k-means, the results from which are further merged with various unstructured data sources, like customer feedback. ML algorithms with the aid of Apache Spark process the immeasurable chunk of interactions happening between users and an e-com platform, which are expressed via complex graphs.

Finance: In finance, Apache Spark is very helpful in detecting fraud or intrusion and for authentication. When used with ML, it can study business expenses of individuals and frame suggestions the bank must give to expose customers to new products and avenues. Moreover, financial problems are indentified fast and accurately. PayPal incorporates ML techniques like neural networks to spot unethical or fraud transactions.

Healthcare: Apache Spark is used to analyze medical history of patients and determine who is prone to which ailment in future. Moreover, to bring down processing time, Spark is applied in genomic data sequencing too.

Media: Several websites use Apache Spark together with MongoDB for better video recommendations to users, which is generated from their historical data.

ML and Apache Spark:

Many enterprises have been working with Apache Spark and ML algorithms for improved results. Yahoo, for example, uses Apache Spark along with ML algorithms to collect innovative topics than can enhance user interest. If only ML is used for this purpose, over 20, 000 lines of code in C or C++ will be needed, but with Apache Spark, the programming code is snipped at 150 lines! Another example is Netflix where Apache Spark is used for real-time streaming, providing better video recommendations to users. Streaming technology is dependent on event data, and Apache Spark ML facilities greatly improve the efficiency of video recommendations.

Spark has a separate library labelled MLib for machine learning, which includes algorithms for classification, collaborative filtering, clustering, dimensionality reduction, etc. Classification is basically sorting things into relevant categories. For example in mails, classification is done on the basis of inbox, draft, sent and so on. Many websites suggest products to users depending on their past purchases – this is collaborative filtering. Other applications offered by Apache Spark Mlib are sentiment analysis and customer segmentation.

Top Things to Know About Scala Programming Language

Posted on December 27, 2018May 23, 2020 by Dexlab

Top Things to Know About Scala Programming Language

Scalable Language, Scala is a general-purpose programming language, both object-oriented and highly functional programming language. It is easy to learn, simple and aids programmers in writing codes in a simple, sophisticated and type-safe manner. It also enables developers and programmers in being more productive.

Even though Scala is a relatively new language, it has garnered enough users and has wide community support – because it’s touted as the most user-friendly language.

About Scala and Its Features

Scala is a completely object-oriented programming language

In Scala, everything is treated as an object. Even, the operations you conduct are termed as a method call. Scala lets you add new operations to already existing classes – thanks to the implicit classes.

One of the best things about Scala is that it makes it effortlessly easy to interact with Java code. You can easily write a Java code inside Scala class – interesting, isn’t it? The Scala makes way for hi-tech component architectures with the help of classes and traits.

Scala is a functional language

No wonder, Scala has implemented top-notch functional programming concepts – in case you don’t know, in functional programming, each and every computation is regarded as a mathematical function. Following are the characteristics of functional programming:

Simplicity
Power and flexibility
Suitable for parallel processing

Not interpreted, Scala is a compiler-based language

As Scala is a compiler based language, its execution is relatively faster than its tailing competitor, Python. The latter is an interpreted language. The compiler in Scala functions just like a Java compiler. It taps the source code and launches Java byte-code that’s executable across any standard JVM (Java Virtual Machine).

Pre-requisites for Mastering Scala

Scala is a fairly simple programming language and there are minimal prerequisites for learning it. If you possess some basic knowledge of C/C++, you can easily start acing Scala. As it is developed upon Java, the fundamental programming functions of Scala are somewhat similar to Java.

Now, if you happen to know about Java syntax or OOPs concept, it would prove better for you to work in Scala.

Basic Scala Terms to Get Acquainted With

Object

An entity which consists of state and behavior is defined as an Object. Best examples – person, table, car etc.

Class

Described as a template or a blueprint for designing different objects that reflects its behavior and properties, a Class is a widely popular term.

Method

It is reckoned as a behavior of a class, where a class may include one or more methods. For example, a deposit can be reckoned as a method of bank class.

Closure

It is defined as any function that ends within the environment in which it’s defined. A closure return value is determined based on the value of one or more variables declared outside the closure.

Traits

These are used to determine object types by mentioning the signature of the supported methods. It is similar to a Java interface.

Things to Remember About Scala

Scala is case sensitive
When saving a Scala program, use “.scala”
Scala execution process begins from main() methods
Never can an identifier name start with numbers. For an instance, the variable name “789salary” is not valid.

Now, if you are interested in understanding the intricacies and subtle nuances of Apache Spark in detail, you have to enroll for Scala certification Training Gurgaon. Such intensive Scala training programs not only help you master the programming language but ensure secure placement assistance.

Databricks Supports Apache Spark 2.4 and Adds ML Runtime

Databricks recently embraced the Apache Spark 2.4, a latest version. They are integrating it into their platform of analytics. Also, the company is on its way to unveil another runtime feature that would simplify the intricacies of deep learning.

Needless to say, Databricks is one of the most powerful supporters of version 2.4 of Spark, the notable stream processing framework. The latest upgraded version features improvement in the performance of machine learning framework running on Spark as well as distributed deep learning. It also includes modifications that would instantly address dependency issues related to deep learning tasks.

Project Hydrogen is an ambitious initiative; it’s under this tag the Spark upgrades were fused and introduced as a new scheduling mode, known as ‘barrier execution’. It encourages developers to embed training in lieu of distributed deep learning posed as an Apache Spark workload.

In context to above, Reynold Xin, a staunch Spark contributor and co-founder at Databricks said, “This is the largest change to Spark’s scheduler since the inception of the project.” He further mentioned that the upgrades will actually help reduce the complexities of machine learning structures and ensure high efficacy.

The latest runtime detail categorized HorovodRunner is developed to rationalize scaling and streamlining of distributed deep learning workloads. It is performed from a single machine to huge clusters. Previously, drifting from single-node workloads to huge distributed training on GPU or CPU clusters needed a bunch of full code rewrites – it was exceedingly challenging enough. Undeniably, HorovodRunner reduces training as well as programming time cutting down them from hours to a few minutes. This was claimed by the professionals working at Databricks.

Besides Horovod, Databricks is found to be saying that its platform offers native integration with TensorFlow, Kera and several other machine learning programs coupled with MLib and GraphFrames super machine learning algorithms.

On top of all this, a few weeks back, Databricks associated itself with a versatile cloud data integrator Talend with a sole aim to integrate the cloud service with their own data analytics platform to allow data scientists leverage the cluster computing framework – it would help process large data sets at scale.

About Apache Spark:

Apache Spark is a robust, well-integrated analytics engine efficient in processing large datasets.

It’s Cracked: Now Increase Your Salary as an IT Professional

Keen to increase your salary – perhaps you’ve accomplished a difficult task and in a position to ask for a salary-hike? Or maybe, it’s time you want to make a switch?

Whatever be the reason, in both the abovementioned cases, the crux is a salary hike – but how to do it well? Salary negotiations are one of the toughest battle fought inside the boardrooms. Interestingly, only 39 percent of professionals even tried to negotiate a higher salary during their last job offer, says a 2018 survey of close to 3,000 people conducted by global staffing firm Robert Half.

Below, we’ve handpicked few of the best ways to enhance your salary without raising an eyebrow – scroll below for such key pieces of advice:

Never Lose Your Calm

Emotional intelligence is to be demonstrated. Not impatience. You are yet to get that job, and your salary negotiation skill is a reflection how you are going to do business, while remaining calm under stressful situations.

Do Your Homework

“Be confident in your own skin! Your salary negotiations can deeply suffer owing to a lack of preparation,” says Jim Johnson, senior vice president at Robert Half Technology. This firm generates an annual salary guide for more than 75 positions in IT field, with data!

In addition, Mr. Johnson supports weighing the competitiveness of your current pay. That’s important. Not only subject to your role or designation, but also to your respective skills, vertical industry and area – including security and data analytics.

Certifications Help

Today, an array of certified and non-certified in-demand skills is available in the market. As a result, IT professionals are found shelling extra pounds for these certifications – an average of 7.6 percent of base salary for a single certification and 9.4 percent of base salary on average for certain single, non-certified skills.

Amidst all, Apache Spark Progamming Training, Data Science, Cryptography and Penetration Testing are the hottest in line. Python Course in Delhi NCR, Artificial Intelligence and Risk Analytics are next to follow.

Other than that, open source skills are quite popular – especially those that concerns DevOps, cloud and containers.

Imbibe Soft Skills As Much As You Can

Developing soft skills is an art! And in this tough age of digital transformation, IT professionals have to constantly to work in cross-functional teams with fellows from different arenas of the business, as well as clients and partners who have zero tech skills.

For this and more, you have to have a good command over English, undying patience and understand people, what they have to say! No wonder, many IT bigwigs say these soft skills are not as soft as they sound – sometimes, it’s really hard to explain and teach people from different parts of the industry.

“It’s funny that we even talk about these skills as ‘soft,’ because they are very hard to master and are frequently the cause of more trouble than lack of ‘hard’ skills,” shares Anders Wallgren, CTO at Electric Cloud.

The ABC Basics of Apache Spark

Posted on November 10, 2018November 10, 2018 by Dexlab

The ABC Basics of Apache Spark

Amazon, Yahoo and eBay has embraced Apache Spark. It’s a technology worth taking a note of. A bulk of organizations prefers running Spark on clusters along with thousands of nodes. Till date, the biggest known cluster consists of more than 8000 nodes.

Introducing Apache Spark

Spark is basically an Apache project tagged as ‘lightning fast cluster computing’. It features a robust open-source community and is the most popular Apache project right now.

Spark is equipped with a faster and better data processing platform. It runs programs faster in memory as well as on disk as compared to Hadoop. Furthermore, Spark lets users write code as quickly as possible – after all, you’ve more than 80 high-level operators for coding!

Key elements of Spark are:

It offers APIs in Java, Scala and Python in support with other languages
Seamlessly integrates with Hadoop ecosystem and other data sources
It runs on clusters controlled by Apache Mesos and Hadoop YARN

Spark core

Ideal for wide-scale parallel and distributed data processing, Spark Core is responsible for:

Communicating with storage systems
Memory management and fault recovery
Arranging, assigning and monitoring jobs present in a cluster

The nuanced concept of RDD (Resilient Distributed Dataset) was first initiated by Spark. An RDD is an unyielding, fault-tolerant versatile collection of objects that are easily operational in parallel. It can include any kind of object, and supports mainly two kinds of operations:

Transformations
Actions

Spark SQL

A major Spark component, SparkSQL queries data either through SQL or through Hive Query Language. It first came into operations as an Apache Hive port to run on top of Spark, replacing MapReduce, but now it’s being integrated with Spark Stack. Along with providing support to numerous data sources, it also fabricates several SQL queries with code transformations, which makes it a very strong and widely-recognized tool.

Spark Streaming:

Ideal for real time processing of streaming data – Spark Streaming receives input data streams, which is then divided into batches only to be processed by Spark engine to unleash final stream of results, all in batches.

Look at the picture below:

The Spark Streaming API resembles Spark Core – as a result, it becomes easier for programmers to tackle for batch and streaming data, effortlessly.

MLib

MLib is a versatile machine learning library that comprises of numerous fetching algorithms that are designed to scale out on a cluster for regression, classification, clustering, collaborative filtering and more. In fact, some of these algorithms specialize in streaming data, such as linear regression using ordinary least squares or k-means clustering.

GraphX

An exhaustive library for fudging graphs and performing graph-parallel operations, GraphX is the most potent tool for ETL and other graphic computations.

Want to learn more on Apache Spark? Spark Training Course in Gurgaon fits the bill. No wonder, Spark simplifies the intensive job of processing high levels of real-time or archived data effortlessly integrating associated advanced capabilities, such as machine learning – hence Apache Spark Certification Training can help you process data faster and efficiently.

The Success Story of Big Data Tooling

Posted on September 17, 2018May 23, 2020 by Dexlab

The Success Story of Big Data Tooling

The world of hadoop data tooling is flourishing. It’s being said, Hadoop is shifting from possible data warehousing to an accomplished big data analytics set-up.

Back in the day, right after Hadoop at Yahoo was first invented, proponents of big data asserted its potential for substituting enterprise data warehouses, framed on business intelligence.

Open source Hadoop data tooling became a preferred choice more as an alternative to those insanely expensive existing systems – as a result, over time, the focus shifted to expanding existing data warehouses and more. Intricate Hadoop applications today are known as data lakes and of late big data tooling is found swelling beyond meager data warehouses.

“We are seeing increasing capabilities on the Hadoop and open source side to take over more and more of the corporation’s data and workloads, including BI,” said Mike Matchett, an analyst and founder of the Small World Big Data consultancy.

Self Service and Big Data

In August, Cloudera launched Workload XM management services designed exclusively for cloud-based analytics. Alternatively, the company built a hybrid Cloudera Data Warehouse and a Cloudera Altus Data Warehouse, capable of running over both Microsoft Azure clouds and AWS.

The main objective of management services is to bring forth some visibility into various data workloads. Workload XM is constructed to aid administrators in presenting reliable service-level agreements for self-service analytics applications – says Anupam Singh, GM of Analytics at Cloudera, Palo Alto, Calif.

Importantly, Singh also mentioned that the cloud warehouse offers encryption for data both at still and in motion, and provides a better view into the trajectory of data sets in analytics workloads. Such potentials have gained momentum and recognition as well as GDPR and other programs.

However, all these discussions boil down to one point, which is how to increase the use of big data analytics. “Customers don’t look at buzzwords like Hadoop and cloud. But they do want more business units to access the data,” he added.

Data on the Wheels

Hadoop player, Hortonworks is a Cloud aficionado. In June, the company broadened its Google Cloud existence with Google Cloud Storage support. Enhancing real-time data analytics and management is a priority.

Meanwhile, in August, Hortonworks churned out Streams Messaging Manager (SMM) with an objective of handling data streaming and provide administrators comprehensive views into Kafka messaging clusters. They have increasingly become popular amongst big data pipelines.

These management tools are crucial for moving Hadoop-inspired big data analytics into production capacities, where in data warehouses fails performing – thus, recommendation engines and fraud detection appears to be a saving grace!

Meanwhile, Kafka-related capabilities in SMM are going on getting advanced and with recently released Hortonworks DataFlow 3.2, the performance for data streaming amplified.

R Adaptability

Similar to its competitors, MapR has bolstered its capabilities beyond its original scope of being used as a mere data warehouse replacement. Early this year, the organizers released a new version of its MapR Data Platform equipped with better streaming data analytics and new item data services that would easily work on cloud as well as premises.

As final thoughts, the horizon of Hadoop is expanding, while data tooling keeps modifying. However, today, unlike before, Hadoop is not only the sole choice for doing data analytics – the choice includes Apache Spark and Machine Learning. All being extremely superior and effective when put to use.

If you are looking for Apache Spark Certification, drop by DexLab Analytics. Their Apache Spark Training program is extremely well-crafted and in sync with industry demands. For more, visit the site.

Hadoop or Spark: Which Big Data Framework to Choose?

Posted on June 25, 2018May 23, 2020 by Dexlab

Hadoop or Spark: Which Big Data Framework to Choose?

Feeling confused?

Of late, Spark has overtaken Hadoop for being the most active open source big data project. Though they have their differences, they both have many common uses.

To begin, they both are incredible big data frameworks. For some years, Hadoop has been leading the open source big data framework clusters but recently highly advanced Spark tends to have captured the market. The latter has become increasingly popular and for all the right reasons. But that is not to say, Hadoop is losing its significance entirely.

They don’t perform exactly the similar tasks. Neither are they mutually exclusive. Though it’s been heard that Spark can work 100X faster than Hadoop in some scenarios, it doesn’t come with its own distributed storage system, which is quite fundamental to big data projects. Distributed storage offers elaborate multi-petabyte dataset storage solution across almost infinite number of computer hard drives. As compared to expensive machinery customization which holds everything in one device, distributed system is cheap as well as scalable, which means as many devices can be added if the network of data set ever grows.

Moreover, Spark doesn’t have its own file system; it cannot organize files in a distributed way without help from third party. This is the reason why several companies think of installing Spark after Hadoop, so that superior analytical applications of Spark can employ data stored using HDFS.

So, what makes Spark win over Hadoop? It’s the SPEED. Spark is a champion of handling a large chunk of its operations ‘in memory’- this reduces a lot of time and effort, indeed. Thanks to MapReduce!

MapReduce writes of the data right to its physical storage medium after each activity. The main purpose of this was to ensure a fully recovery if something goes wrong – nevertheless, Spark organizes data in Resilient Distributed Datasets, where data can be easily recovered following failure or any kind of mishap.

The main driving factor behind growth of Spark lies in its adept functionality for tackling advanced data processing tasks, including machine learning and real-time stream processing. Real-time processing stands for feeding data into analytical applications the moment it’s seized, and insights are right away directed back to the users through a dashboard to inspire action. This kind of processing is nowadays very much used in big data, thus making Spark enjoy an upper hand against its Hadoop counterpart.

The technology of machine learning is right at the kernel of digital revolution – artificial intelligence and creating far-fetched algorithms is an area of analytics Spark excels at. Its speed and the sound capability to tackle streaming data are the reasons behind. Spark has its own machine learning libraries, known as MLib, while Hadoop needs to collaborate with third-party machine learning library, for example Apache Mahout.

As closing thoughts, though it appears that the two big data frameworks are stiff competitors of each other, yet this is really not the case in the reality. The corporate uses offers both the application services, letting the buyer decide which one they prefer to pick, subject to their functionality and need.
