> 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
> Assignee: Gopal V
> Attachments: HIVE-16571.patch
>
>
> 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.
