Chris Trezzo commented on MAPREDUCE-5951:
-----------------------------------------
Another note about removal of the release api: Without the release api, long
running applications will not be able to release resources they are no longer
using. Their appId will be claiming that resource until the application is
finished.
> 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).
