Hadoop Common  is a collection of common libraries and utilities that work with different Hadoop modules.  It is an essential component or component of the Apache Hadoop Framework, along with the Hadoop Distributed File System (HDFS) and the Hadoop YARN as well as Hadoop MapReduce.

As with all modules Hadoop Common is based on the assumption that hardware failures are not uncommon and that they are automatically dealt with in software using Hadoop Framework. Hadoop Framework.

Hadoop Common can also be referred to by the name Hadoop Core.

Hadoop Client library aid in loading files into clusters. They also then submit Map Reduce jobs describing how the data will be handled, and look up the outcomes of the task when it's completed.
