> 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?
