Release Note

Support for shell profiles has been added. They allow for easy integration of additional functionality, classpaths, and more from inside the bash scripts rather than relying upon modifying hadoop-env.sh, etc. See the Unix Shell Guide for more information.

Description

It would be useful to provide a way for core and non-core Hadoop components to plug into the shell infrastructure. This would allow us to pull the HDFS, MapReduce, and YARN shell functions out of hadoop-functions.sh. Additionally, it should let 3rd parties such as HBase influence things like classpaths at runtime.
