Aihua Xu commented on HIVE-14037:
---------------------------------
Thanks. hive.aux.jars.path uses tmpjars to pass the local jar info and then
hadoop will copy those jars to hdfs and distribute them to other nodes. Seems
like we should do the same thing. I'm investigating that and will give you
updates.
Just to confirm with you if you were aware of the issue.
