Subject [jira] [Commented] (HADOOP-10668) TestZKFailoverControllerStress#testExpireBackAndForth occasionally fails
Date Tue, 10 Jun 2014 22:47:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10668?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14027165#comment-14027165
] 

Chris Nauroth commented on HADOOP-10668:
----------------------------------------

It looks like upgrading ZooKeeper didn't fix this.  Here is a Jenkins build after HADOOP-9555
was committed, showing a failure in {{TestZKFailoverController#testAutoFailoverOnLostZKSession}}.

https://builds.apache.org/job/PreCommit-HADOOP-Build/4039/

Let's keep HADOOP-10668 open.
