{code}
When tez reuse container is enable, and use MapJoinOperator, if same tasks's
different taskattemp execute in same container, will throw NPE.
By my debug, I found the second task attempt use first task's
asyncInitOperations. asyncInitOperations are not clear when close op, then
second taskattemp may use first taskattepmt's mapJoinTables which
HybridHashTableContainer.HashPartition is closed, so throw NPE.
We must clear asyncInitOperations when op is closed.
