Chris Trezzo commented on MAPREDUCE-5951:
-----------------------------------------

Note: currently this patch depends on how YARN-3637 is implemented. I will 
adjust this patch once it is committed.

> Add support for the YARN Shared Cache

> Implement the necessary changes so that the MapReduce application can 
> leverage the new YARN shared cache (i.e. YARN-1492).
> Specifically, allow per-job configuration so that MapReduce jobs can specify 
> which set of resources they would like to cache (i.e. jobjar, libjars, 
> archives, files).
