>
> If dynamic partition insert generates multiple partitions and some partitions
> need to be merge (MR task) and some need not (move task), parallel execution
> could cause the move task finish first and created the partition directory
> (say ds=1) first. When the MR job finished, it created a different directory
> (ds=1_1) for the same partition ds=1.
