> Found this problem on beasting LeaderVoteWaitTimeout,
> * a replica publish itself as DOWN on RecoveryStrategy.pingLeader()
> * It won the election (by vote wait timeout) then skipping publish itself as ACTIVE (by looking into clusterstate, its state still ACTIVE).
> * ends up with a leader with DOWN state!
> Therefore, replica should look into both clusterstate and its local last published state.
