Subject [jira] [Commented] (HIVE-17401) Hive session idle timeout doesn't function properly
Date Tue, 05 Sep 2017 16:40:00 GMT


Xuefu Zhang commented on HIVE-17401:

Hi [~pvary], Thanks for the review. I think your suggestion makes sense except that we have
to initialize {{lastAccessTime}} to current time (instead of 0). Otherwise, there is a slim
chance that a session gets timed out before it's completed opened.

I will post a new patch for this.

> It's apparent in our production environment that HS2 leaks sessions, which at least contributed
to memory leaks in HS2. We further found that idle HS2 sessions rarely get timed out and the
number of live session keeps increasing as time goes on. Eventually, HS2 becomes irresponsive
and demands a restart.
> Investigation shows that session idle timeout doesn't work appropriately.
