          I'm planning on upgrading us to the recently released ZooKeeper 3.4.6 as part of HADOOP-9555. It would be interesting to see if we still have this problem after the upgrade.

          I've committed HADOOP-9555. I've run TestZKFailoverControllerStress multiple times with no failures. Maybe the ZooKeeper upgrade fixed this by side effect. Ted, do you have a consistent repro, or were you only seeing it on Jenkins? If so, then maybe we need to wait and see how the test behaves on Jenkins over the next several days.

          I saw the test failure on Jenkins.

          Will keep an eye on Jenkins in the future.

          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.

          It appears the check whether a node is in the right state could be the issue. ZKFailoverController has its own serviceState. HA service such as DummyHAService has its own state. What happened here is MiniZKFCCluster's waitForHAState uses DummyHAService state to decide the state has transitioned properly. But when fencing is involved, the to-be-elected active will directly call the old active's transitionToStandby method. Thus DummyHAService's state could be set to standby before ZKFailoverController's state is updated.

          The patch didn't change the fact ZKFailoverController's state is only updated when it receives notification from ZK callback. So with the fix, it might still get the following error in the log. But that is ok, ZKFailoverController's state eventually will be changed to standby.

          2015-01-12 15:08:16,497 ERROR ha.ZKFailoverController (ZKFailoverController.java:verifyChangedServiceState(828)) - Local service DummyHAService #1 has changed the serviceState to standby. Expected was active. Quitting election marking fencing necessary.

          Thanks, Chris. Sorry, I didn't update TestZKFailoverController test cases that rely on the old behavior of MiniZKFCCluster#waitForHAState. It is strange how it passed the jenkins build above. Here is the addendum patch.

          Ming, thank you for the addendum patch. I committed it to trunk and branch-2.

          Looking back at the Jenkins output, it appears that there was some error while trying to identify the subset of test modules to execute, so in reality it didn't run any tests. I don't know if this is happening often, so we'll have to watch out for it. The tell-tale sign is the text "patch passed unit tests in", followed by a blank list instead of the sub-modules.

          cnauroth Chris Nauroth added a comment - Ming, thank you for the addendum patch. I committed it to trunk and branch-2. Looking back at the Jenkins output, it appears that there was some error while trying to identify the subset of test modules to execute, so in reality it didn't run any tests.
