--------------------------------
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?
