Detect regionserver failure as fast as reasonable. Set the following
parameters:
* In `hbase-site.xml`, set `zookeeper.session.timeout` to 30 seconds or less
to bound failure detection (20-30 seconds is a good start).
-- Notice: the `sessionTimeout` of zookeeper is limited between 2 times and 20
times the `tickTime`(the basic time unit in milliseconds used by ZooKeeper.the
default value is 2000ms.It is used to do heartbeats and the minimum session
timeout will be twice the tickTime).
+- Note: Zookeeper clients negotiate a session timeout with the server during
client init. Server enforces this timeout to be in the
+range [`minSessionTimeout`, `maxSessionTimeout`] and both these timeouts are
configurable in Zookeeper service configuration.
Review comment:
Added the time unit.
