Subject [jira] [Commented] (HADOOP-8257) Auto-HA: TestZKFailoverControllerStress occasionally fails with Mockito error
Date Fri, 06 Apr 2012 22:16:17 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248928#comment-13248928

Todd Lipcon commented on HADOOP-8257:

Jenkins won't run on this since it's on a branch. I verified by changing the test runtime
to 3 seconds and looping it. Without the patch, it failed with the mockito error after 3 or
4 minutes. I then looped with the patch for 15 minutes without a failure.

 E.g. thenReturn() may be missing....
> This is because we set up the mock answers _after_ starting the ZKFCs. So if the ZKFC
calls the mock object while it's in the middle of the setup, this exception occurs.
