----------------------------------------
Summary: ZooKeeper server binds to all ip addresses for leader
election and broadcast
Key: ZOOKEEPER-1711
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1711
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.4.5
Environment: Any
Reporter: Germán Blanco
Priority: Minor
Fix For: 3.4.6
Unlike current ZooKeeper version in trunk intended for release as 3.5.0, the
current ZooKeeper server version 3.4.5 binds to all ip addresses on the
specified port for election. It only makes sense to bind to the ip address
indicated in the configuration file, which is where the other servers will
connect. Listening to other ip addresses could have bad security implications.
