Peter Vary commented on HIVE-22964:
-----------------------------------
The pool could be leaked with HIVE-22964.2.patch if there is an Throwable is
thrown in {{pool.submit()}} for whatever reason.
Uploaded the one I have been trying to propose, but seems I was not clear
enough :)
+1 from my side for HIVE-22964.3.patch, if you agree with my change.
Thanks for the patience!

> Since for MM table we process the paths prior to inputFormat.getSplits() we
> end up doing listing on the whole table at once. This could be optimized.
