What is Apache Hadoop ?
Apache Hadoop is A powerful framework that provides a large collection of utilities for supporting reliable, scalable, distributed data processing operations .
Apache Hadoop was initially developed by Yahoo and the project is a combination between the previous Apache Hadoop Core and Apache Hadoop Common repos.The Hadoop project has gained a lot of notoriety thanks to its great results in implementing a multi-server distributed computing system for handling huge amounts of data.The project itself is actually made of four parts. One is Hadoop Common, the so called core that allows all other modules to work, the second is its very own filesystem – HDFS (Hadoop Distributed File System), the third is the Hadoop YARN scheduling framework, and finally there is the Hadoop MapReduce system for supporting parallel computing.Using these ground breaking system, the Apache has managed to create many other side projects, like:- Apache Ambari- Apache Avro- Apache Cassandra- Apache HBase- Apache Hive- Apache Mahout- Apache Pig- Apache Spark- Apache Tez- Apache ZooKeeperAll of these rely on Hadoop’s powerful data processing engine or its distributed computing features, integrating one of its modules in their core’s one way or the other.
