Vikram Dixit K updated HIVE-10647:
----------------------------------
Attachment: HIVE-10647.2.patch
Changed to use a semaphore. I do not see a specific need to grow the size
beyond 1 in the default case because:
1. If it is the cli mode, the user basically never lets go of the session and 1
is all they need.
2. If it is hs2, the user needs to configure this correctly anyways.
I can change it to a large number but don't really see a good reason for it.
> Hive on LLAP: Limit HS2 from overwhelming LLAP
