Peter Vary commented on HIVE-20179:
-----------------------------------
[~prasanth_j], [~sershe]: Could you please take a look? I would like to find a
solution for the problem, that if I want to start HS2 (I do not use Tez), it
fails for the first time, and keeps forever to accept requests. Is the proposed
solution OK? Would it cause any problems on Tez side?
Thanks,
Peter
