Sergey Shelukhin commented on HBASE-8785:
-----------------------------------------
That is if maxSessionTimeout defined on ZK, not in our config.
I was running integration tests and saw that negotiated timeout is 40s., coming
from ZK (tick * 20?)
So at least the comment needs to be changed imo.
> revise zookeeper session timeout setting

> Key: HBASE-8785
> URL: https://issues.apache.org/jira/browse/HBASE-8785
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.95.1
> Reporter: Sergey Shelukhin
> Fix For: 0.95.2
>
>
> Current ZK session timeout is set to 90sec., and the comment in the doc says:
> "This setting becomes zookeeper's 'maxSessionTimeout'". However, this comment
> is misleading - it doesn't always become maxSessionTimeout, min(our timeout,
> maxSessionTimeout) is chosen. Moreover, the default maxSessionTimeout in ZK
> that I'm looking at is 40s, so this setting doesn't do anything.
> Additionally, 40s. seems like a lot of time.
> 1) Should the comment be changed to tell the user to change ZK config if they
> want higher timeout?
> 2) Should the setting be revised down?
