> Remove Master Recovery handling when ZK session expired
> -------------------------------------------------------
>
> Key: HBASE-9932
> URL: https://issues.apache.org/jira/browse/HBASE-9932
> Project: HBase
> Issue Type: Brainstorming
> Reporter: Jeffrey Zhong
>
> Currently we use HMaster#tryRecoveringExpiredZKSession to allow master
> recovery from a ZK session expired error. While this triggers to initialize
> HMaster partially, it is error prone because it's hard to guarantee the half
> initialized master is in correct state. I found several times already that
> the registered ZK listeners are different before & after a fail over.
> Since we already have HA support, I'm proposing to remove this part handling.
> Though we have a configuration setting "fail.fast.expired.active.master" to
> skip the logic, why not go one stop further to clean the master code.
