Chris Trezzo commented on MAPREDUCE-5951:
-----------------------------------------
This is the javac warning:
{noformat}
[WARNING]
/testptch/hadoop/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-common/src/main/java/org/apache/hadoop/mapreduce/v2/util/LocalResourceBuilder.java:[34,44]
[deprecation] DistributedCache in org.apache.hadoop.mapreduce.filecache has
been deprecated
{noformat}
LocalResourceBuilder was a class added to fix a checkstyle warning. I have used
{{@SuppressWarnings("deprecation")}} to silence the warnings around
DistributedCache usage at the class level. This warning is complaining about
the import statement. If anyone has an idea for how to apply the annotation to
the import statement, please let me know. Furthermore, the LocalResourceBuilder
is simply refactoring the MRApps#parseDistributedCacheArtifacts method, so I do
not think it makes sense to fix the usage of a deprecated interface in this
patch, especially since it is used in a lot of places.

> 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).
