Brock Noland commented on HIVE-9625:
------------------------------------
[~thejas] [~prasadm] - do agree that these tokens do not have a renew process
at present? If so, I think we can add a background thread to renew them in
[SessionManager|https://github.com/apache/hive/blob/trunk/service/src/java/org/apache/hive/service/cli/session/SessionManager.java#L150].
> Delegation tokens for HMS are not renewed
