Bikas Saha commented on MAPREDUCE-5403:
---------------------------------------
>From what I understand its meant for applications to setup up their classpath
>to include yarn/hdfs/common/etc jars. Since YARN is language agnostic, this
>tweak helps setup java applications. This is used by TEZ to setup the
>classpath correctly. We should probably fix MR to use this if it already not
>doing so.
> Get rid of yarn.application.classpath

> yarn.application.classpath is a confusing property because it is used by
> MapReduce and not YARN, and MapReduce already has
> mapreduce.application.classpath, which provides the same functionality.
