> Project: Hive
> Issue Type: Bug

>
> The current implementation of FileSinkOperator runs into trouble when reusing
> the same query pipeline aggressively with container reuse.
> This is due to a prevFSP writer which is left referenced after closeOp() and
> which is not reset even for initializeOp().
