Unfortunately doesn't look like we have enough logging going on there.
For example would be nice to know what's the committed config and last seen
config
of the leader when it comes up (leader.lead()). and what configuration is
sent in the NEWLEADER message
sent out in LeaderHandler:
QuorumPacket newLeaderQP = new
QuorumPacket(Leader.NEWLEADER,
newLeaderZxid,
leader.self.getLastSeenQuorumVerifier()
.toString().getBytes(), null);
I didn't know about the option to have a separate administrative interface,
and just followed the flow of other commands... I agree that it would be
cleaner.
