Description
if specify -libjar -files -archive on command line or set below properties
mapreduce.job.cache.archives mapreduce.job.cache.files.filesizes
MapReduce framework will configure LocalResources for map/reduce container. also configure for ApplicationMaster.
if job is not uber, ApplicationMaster does not need LocalResources.
Deploying localResource for AM will cause slowly launching AM.
I make a proposal: if job is not uber, map-reduce client does not configure localResource for AM. obviously must configure for map/reduce container.
