Hadoop Developer Job Description

Hadoop is a framework used for distributed computing, based on a paradigm of processing large datasets across clusters of commodity servers using simple software frameworks.

Hadoop was originally developed by Yahoo! Research in 2004 as a successor to their File System Redeemable Block Store (FS-RBSTM).

In 2009, Yahoo! sold the Hadoop trademark to Hortonworks, which introduced the Hortonworks Data Platform.

Hadoop is already widely used by large organizations for large-scale data processing.
