Subject [jira] [Commented] (ZOOKEEPER-1805) "Don't care" value in ZooKeeper election breaks rolling upgrades
Date Mon, 04 Nov 2013 11:45:46 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-1805?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13812776#comment-13812776
] 

Flavio Junqueira commented on ZOOKEEPER-1805:
---------------------------------------------

It still bothers me that we can't distinguish between old and new notification messages. I
was thinking about introducing a format version field so that we can get around this problem
and make the check in the way proposed instead of working around it.

I have a patch mostly ready, but I'd like to know if this a direction that is ok to pursue.
If this ok, then I can add a sub-task here so that we can work this out separately, before
fixing this issue.
