Gopal V commented on HIVE-16571:
--------------------------------

Tested this on the cluster, works exactly as expected - most recently used session gets used
again.

> Currently Tez session reuse is entirely round-robin, which means a single user might
have to run upto 32 queries before reusing a warm session on a HiveServer2.
> This is not the case when session reuse is disabled, with a user warming up their session
on the 1st query.
