Ferdinand Xu commented on HIVE-14037:
-------------------------------------
Thanks [~aihuaxu] reaching me about this. It may be an issue in other non HS2
node since newly added jars are not distributed to these nodes. I am not so
sure whether there is a better solution than tmpjars of JobConf. Maybe we could
have a try in this way.
> java.lang.ClassNotFoundException for the jar in hive.reloadable.aux.jars.path
