             Summary: Fix TestSCMSafeModeWithPipelineRules
                 Key: HDDS-2491
                 URL: https://issues.apache.org/jira/browse/HDDS-2491
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
    Affects Versions: 0.4.1
            Reporter: Xiaoyu Yao


This was based on [~sammichen]'s investigation on HDDS-2034.

 
{quote}The root cause is failing to exit the safemode. Current pipeline open condition(HDDS-1868) is got 3 datanode reports and one datanode marked itself as leader. In this failure case, the leader election succeeds while XceiverServerRatis#handleLeaderChangedNotification is not called in the next 3 minutes. So cluster.waitForClusterToBeReady() timeout.
The question is is this Leader change notification reliable? What's the expected latency between leader election succeed and notification send?
