> {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?
