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.
> RSC has memory leak while execute multi queries.[Spark Branch]
