Review request for hive.


Bugs: HIVE-10006
    https://issues.apache.org/jira/browse/HIVE-10006


Repository: hive


Description
-------

In RSC, while spark call CombineHiveInputFormat::getSplits to split the job into tasks in a thread called "dag-scheduler-event-loop", MapWork would be added to a ThreadLocal map of "dag-scheduler-event-loop", and never get removed. As the "dag-scheduler-event-loop" thread is a long live and daemon thread, so all the MapWorks would be hold in the ThreadLocal map until RSC jvm crash or exit.
