Germán Blanco commented on ZOOKEEPER-1096:
------------------------------------------
Wouldn't it make sense to apply this also for the leader election port (at
least for Fast Leader Election)?
And I also would like to have it in 3.4.6, if there is no problem.
> Leader communication should listen on specified IP, not wildcard address

> Server should specify the local address that is used for leader communication
> (and not use the default of listening on all interfaces). This is similar to
> the clientPortAddress parameter that was added a year ago. After reviewing
> the code, we can't think of a reason why only the port would be used with the
> wildcard interface, when servers are already connecting specifically to that
> interface anyway.
> I have submitted a patch, but it does not account for all leader election
> algorithms.
> Probably should have an option to toggle this, for backwards compatibility,
> although it seems like it would be a bug if this change broke things.
> There is some more information about making it an option here:
