Subject [jira] [Commented] (HIVE-10006) RSC has memory leak while execute multi queries.[Spark Branch]

Chengxiang Li commented on HIVE-10006:
--------------------------------------

Basically, i just clear the MapWork cached in ThreadLocal, it would not influence any function,
as hive can always get MapWork through disk or hadoop distributed cache, and i cann't reproduce
these 2 failed qtests locally, upload the patch to test again.
