---------------------------------------
Summary: 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?
