Ming Ma commented on MAPREDUCE-5951:
------------------------------------
Thanks [~ctrezzo]. The code looks good overall. The only question I have at
this point is if any code should be moved from MR to YARN to make it easier for
other YARN applications to use shared cache. For example, maybe other
applications can benefit from part of LocalResourceBuilder or the special care
when dealing with fragment.

> 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).
