It is<strong> Java-based<\/strong> and uses <strong>Hadoop Distributed File System<\/strong> (<strong>HDFS<\/strong>) to store its data and process data using <strong>MapReduce<\/strong>.<\/p>\n\n\n\n<div class=\"wp-block-spacer\" style=\"height: 30px;\" >\u00a0<\/div>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/uploads\/2022\/12\/saas.png\" alt=\"saas services\" class=\"wp-image-3972\" width=\"256\" height=\"256\"\/><\/figure>\n\n\n\n<div class=\"wp-block-spacer\" style=\"height: 30px;\" >\u00a0<\/div>\n\n\n\n<p>Apache Hadoop plays an important role after performing the <strong>ETL (<a href=\"https:\/\/www.ibm.com\/topics\/etl\">Extract Transform Load<\/a>)<\/strong> steps in order to store the result in order to process or use it for <strong>analysis<\/strong>. Storing the data will not be easy because the size can be from <strong>gigabytes<\/strong> to <strong>petabytes<\/strong> (as mentioned in the above paragraph) and after storing it then make a backup of it so can be used later if 1 node stopped working. Apache Hadoop is a Java-based software platform that helps in <strong><a href=\"\/managed-vs-unmanaged-hosting-solutions\/\">managing data<\/a><\/strong> such as <strong>processing data <\/strong>and <strong>making replicas<\/strong> (<strong>backups<\/strong>) of it, etc.<\/p>\n\n\n\n<div class=\"wp-block-spacer\" style=\"height: 30px;\" >\u00a0<\/div>\n\n\n\n<div id=\"setup-apache-hadoop-283\">&nbsp;<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">2.
