Let\u2019s go over some of the reasons why people want to use it:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Simplicity:<\/strong> As an Object-oriented language Java offers quite an easy user experience for developers as well as end-users. Java&#8217;s inbuilt design is its most significant advantage when compared with other similar object-oriented programming languages. Unlike C++ it has removed the use of pointers and interface.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Portability:<\/strong> Java runtime can be run anytime and anywhere. Hence, you can run Java on any hardware and software platform.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Allocation:<\/strong> Java has a stack provisioning feature that helps to re-establish quickly. Moreover, Java has the potential for garbage collection and automatic memory distribution.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Distributive:<\/strong> Java is highly networking competent. Usually, Java receives and sends files informally.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Extremely secure:<\/strong> Java enforces strong security standards with safe programming. <\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><em><span style=\"font-weight: 400;\">Now, let\u2019s see where Java fits with big data in reality.<\/span><\/em><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Nowadays the amount of data produced every day shows exponential growth. Moreover, analyzing such a vast amount of data will only continue to increase over the period as well. Batch data processing is a realistic way of analyzing such vast data, and this is mostly done using open source tools like Hadoop and Spark.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Interestingly most of the open-source big data tools are Java-based. One of the key reasons behind it is the root of Java is deeply ingrained in open-source communities. Hence, a huge amount of Java code is publicly available, and with these readily available code foundations like Apache, Google is hugely contributing to making open source big data tools.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">For the most prominent big data tool Hadoop, Java is the language. Hence, it is easy for Java developers to learn Hadoop. The fact is learning some of the big data tools are almost similar to learning a new API for Java developers.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Not only Hadoop, but Pig is also another big data tool for Java developers which they can learn easily as Pig Latin uses JavaScript.<\/span><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Best_Open_Source_Big_Data_Tools_for_Java_Developers_in_Market\"><\/span><b>Best Open Source Big Data Tools for Java Developers in Market<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">No doubt, future of big data is Java. There are numerous big data tools for Java developers in the market, and most of them are open source from Apache. Here we have sorted out some of them which are mostly used big data tools for Java developers.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"1_Apache_Hadoop\"><\/span><b>1. Apache Hadoop<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Hadoop is a Java subproject and mostly used big data tools. It is an Apache Software Foundation tool which was later donated by Yahoo! It is a free, Java-based programming framework which processes large datasets in a distributed computing environment. In addition to that, you can easily install it on a cluster of standard machines. Hadoop has become very successful in companies for storing massive data in one system and performing analysis on this data. Hadoop runs in master\/slave architecture. The master controls the running of the entire distributed computing stack.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Hadoop has an entire ecosystem of software built around it.<\/span><\/p>\n<p style=\"text-align: justify;\"><img decoding=\"async\" class=\"alignnone size-full wp-image-66788\" src=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/sites\/2\/2018\/07\/hadoop2.jpg\" alt=\"apache hadoop\" width=\"891\" height=\"541\" srcset=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop2.jpg 891w, https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop2-300x182.jpg 300w, https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop2-768x466.jpg 768w, https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop2-692x420.jpg 692w, https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop2-640x389.jpg 640w, https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop2-681x413.jpg 681w\" sizes=\"(max-width: 891px) 100vw, 891px\" \/><\/p>\n<p style=\"text-align: justify;\"><b><i>Important features of Hadoop are listed below.<\/i><\/b><\/p>\n<p style=\"text-align: justify;\"><img decoding=\"async\" class=\"size-full wp-image-66789 aligncenter\" src=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/sites\/2\/2018\/07\/hadoop-features.png\" alt=\"hadoop features\" width=\"592\" height=\"285\" srcset=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop-features.png 592w, https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2018\/07\/hadoop-features-300x144.png 300w\" sizes=\"(max-width: 592px) 100vw, 592px\" \/><\/p>\n<blockquote>\n<p style=\"text-align: justify;\"><i><span style=\"font-weight: 400;\">If you want to know more details on Hadoop architecture and other details, please refer to our <a href=\"https:\/\/www.whizlabs.com\/blog\/learning-hadoop-for-beginners\/\" target=\"_blank\" rel=\"noopener\">Hadoop guide for beginners<\/a>.<\/span><\/i><\/p>\n<\/blockquote>\n<h3 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"2_Apache_Spark\"><\/span><b>2.

Spark is a cluster computing framework and can run on thousands of machines. Furthermore, it can run on a cluster of distributed computers on the massive datasets across these computers and combine the results. Spark stands on the concept of RDD (Resilient Distributed Dataset).<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Spark is used in large ETL (extract, transform, and load) operation, predictive analytics, and reporting applications. A Spark program would do the following:<\/span><\/p>\n<ol style=\"text-align: justify;\">\n<li><span style=\"font-weight: 400;\"> It loads some data into the RDD.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Performs the transformation on data to make it compatible for handling your\u00a0<\/span>operations.<\/li>\n<li><span style=\"font-weight: 400;\"> Cache the reusable data across sessions (by using persist).<\/span><\/li>\n<li><span style=\"font-weight: 400;\"> Do some readymade or custom operations on the data.<\/span><\/li>\n<\/ol>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">The underlying language used for Spark is Scala, which inherently is written in Java.
