Alexandre Hardy commented on ZOOKEEPER-917:
-------------------------------------------
Sorry, that should have been 192.168.130.13, not 192.168.130.11.
> Leader election selected incorrect leader

> Key: ZOOKEEPER-917
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-917
> Project: Zookeeper
> Issue Type: Bug
> Components: leaderElection, server
> Affects Versions: 3.2.2
> Environment: Cloudera distribution of zookeeper (patched to never
> cache DNS entries)
> Debian lenny
> Reporter: Alexandre Hardy
> Priority: Critical
> Attachments: zklogs-20101102144159SAST.tar.gz
>
>
> We had three nodes running zookeeper:
> * 192.168.130.10
> * 192.168.130.11
> * 192.168.130.14
> 192.168.130.11 failed, and was replaced by a new node 192.168.130.13
> (automated startup). The new node had not participated in any zookeeper
> quorum previously. The node 192.148.130.11 was permanently removed from
> service and could not contribute to the quorum any further (powered off).
> DNS entries were updated for the new node to allow all the zookeeper servers
> to find the new node.
> The new node 192.168.130.13 was selected as the LEADER, despite the fact that
> it had not seen the latest zxid.
> This particular problem has not been verified with later versions of
> zookeeper, and no attempt has been made to reproduce this problem as yet.
