Robert Joseph Evans commented on MAPREDUCE-5087:
------------------------------------------------

+1 for the idea but lets move it out of Map/Reduce and put it in common, or 
YARN.  I ran into this recently writing an AM for storm.  I would love to use 
this instead of (ctl-c, ctl-v), but I don't really want to depend on the MR 
jars if I am not doing MR processing, and I assume others feel similarly.

> The facilities behind JobConf#setJarByClass and the JarFinder utility in test 
> are both generally useful. As the core platform, these should be published as 
> part of the public API. In addition to HBase, they are probably useful for 
> Pig and Hive as well. See also HBASE-2588, HBASE-5317, HBASE-8140.
