[jira] [Created] (ZOOKEEPER-1894) ObserverTest.testObserver fails consistently

Michi Mutsuzaki created ZOOKEEPER-1894:
------------------------------------------

             Summary: ObserverTest.testObserver fails consistently
                 Key: ZOOKEEPER-1894
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1894
             Project: ZooKeeper
          Issue Type: Bug
          Components: quorum
    Affects Versions: 3.5.0
         Environment: ubuntu 13.10
Server environment:java.version=1.7.0_51
Server environment:java.vendor=Oracle Corporation
            Reporter: Michi Mutsuzaki
             Fix For: 3.5.0


ObserverTest.testObserver fails consistently on my box. It looks like the observer (myid:3) calls QuorumPeer.getQuorumVerifier() in a tight loop, and the leader (myid:2) is not getting enough CPU time to synchronize with the follower and the observer. The test passes if I increase ClientBase.CONNECTION_TIMEOUT from 30 seconds to 120 seconds. I'll attach a log file.
