> Given three nodes, the leader on 2, but some issue with this machine, so I shutdown this machine, and change the host name to another machine.
> Then I start the node in the new machine, but the new node can not join.
> I found the the 1 and 3's Listener thread exit.
> With the code of Listener's run method:
> I think we should catch UnresolvedAddressException to avoid the Listener exit.
