Subramanyam Pattipaka commented on HIVE-15803:
----------------------------------------------
[~rajesh.balamohan] and [~ashutoshc], instead of simply passing null to
recursive call, can we maintain an atomic counter and pass null as soon we see
number of threads in the pool are over. That way we can best utilize the
threads.
> msck can hang when nested partitions are present
