What is Beyond Classic Hadoop? Is it Spark and Flink? In this blog, we will explore the two new big data friends to Hadoop, and they are Apache Spark and Apache Flink. And if we take the Hadoop improvements with the parallel processing MapReduce; speed is very first focus. However, MapReduce is designed and developed for […]

Scalable Apache Spark Solution to Big Data Secondary Sort Problem! – Part 1 In Big Data era the secondary sort problem is relates to sorting values associated with a key in the reduce phase. It can be called as value-to-key conversion. The secondary sorting technique will help us to sort the values in ascending or […]
Relationship between MapReduce, Spark, YARN, and HDFS ! In Big Data era Hadoop is the de facto standard for developing of big data applications by using MapReduce framework. And Hadoop is composed of one or more master nodes and any number of slave nodes depends up on the data needed. Hadoop simplifies distributed applications by […]

This blog introduces the convergence of complementary technologies – Spark, Mesos, Akka, Cassandra and Kafka (SMACK) stack. And we will see how Apache Kafka can help us to get data under control and what is it role in our data pipeline, how Spark & Akka help us to process the data, and how Cassandra to […]
Blog 4 – OOP to Functional Programming We are already using functional programming using Scala with the previous blog series of Self-Learn Yourself Scala in 21 Blogs (#1, #2, #3). Let’s start with defining functional programming which is a programming paradigm that models computation as the evaluation of expressions and expressions are built using functions […]
Blog 3 – Functional Programming & Data Structures In Scala Functional programming and functional data structures are very interesting and powerful. Actually it supports both types data structures called immutable & mutable. And let us discuss on two more vital concepts called type parameterization and higher-order functions. The type is similar to Java generics; it […]
