> 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.
