Subject [jira] [Commented] (CURATOR-47) Two leaders in the leader election recipe
Date Mon, 15 Jul 2013 11:34:48 GMT

Germán Blanco commented on CURATOR-47:
--------------------------------------

Ah!
I have seen that thread, you may have noticed that I am the one responding at your mail :-D
In any case, I hope that you agree that rolling restart needs to be supported. And whatever
failure occurs during a rolling restart may also happen during normal operation at some point.
My guess is that this specific failure (if it is really a failure) is related with stopping
the leader of the BC Cluster.

Kind regards,

Germán.

> When using the Leader Election recipe and doing a rolling restart of the zookeeper servers
in the cluster, it seems that at some points there are two participants that see themselves
as leaders.
