[jira] [Commented] (CURATOR-47) Two leaders in the leader election recipe

    [ https://issues.apache.org/jira/browse/CURATOR-47?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13706892#comment-13706892 ] 

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

The following trace is seen when running TestLeaderElection.java:
ERROR [LeaderSelector-0:TestLeaderElection@154] - I am 0 have leadership is true and the leader is 1

It seems that it is actually not required to modify the tickTime in order to see this.

> 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.
