> In case of dynamic partition insert, FileSinkOperator generated a directory
> for a new partition and the files in the directory is named with '_tmp*'.
> When a task succeed, the file is renamed to remove the "_tmp", which
> essentially implement the "commit" semantics. A lot of exceptions could
> happen (process got killed, machine dies etc.) could left the _tmp files
> exist in the DP directory. These _tmp files should be deleted ("rolled back")
> at successful jobClose(). After the deletion, we should also delete any empty
> directories.
