Ashutosh Chauhan commented on HIVE-15803:
-----------------------------------------
[~nandakumar131] Trouble with list of pool is, its unbounded, in pathological
case of large number of levels, we will have large number of pools each having
its own set of threads. I like [~pattipaka] suggestion better of using counter
that we get sharing as much as possible with predefined number of threads.
Would you like to create a patch with that approach?
