Leader communication should listen on specified IP, not wildcard address
------------------------------------------------------------------------
Key: ZOOKEEPER-1096
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1096
Project: ZooKeeper
Issue Type: Improvement
Components: server
Affects Versions: 3.3.3, 3.4.0
Reporter: Jared Cantwell
Priority: Minor
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:
