> 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.
