Rohini Palaniswamy commented on HCATALOG-302:
---------------------------------------------
As you said I had missed adding it to tmpjars. Will upload the patch along with
302. The unit tests passed as MiniMRCluster launches tasks with classpath
including the classpath it was launched with. So this got missed.
