             Summary: HiveServer2: Prefer LIFO over round-robin for Tez session reuse
                 Key: HIVE-16571
                 URL: https://issues.apache.org/jira/browse/HIVE-16571
             Project: Hive
          Issue Type: Improvement
          Components: HiveServer2, Tez
    Affects Versions: 3.0.0
            Reporter: Gopal V


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.
