             Summary: GC other system pause events can trigger pipeline destroy for all the nodes in the cluster
                 Key: HDDS-1454
                 URL: https://issues.apache.org/jira/browse/HDDS-1454
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: SCM
    Affects Versions: 0.3.0
            Reporter: Mukul Kumar Singh


In a MiniOzoneChaosCluster run it was observed that events like GC pauses or any other pauses in SCM can mark all the datanodes as stale in SCM. This will trigger multiple pipeline destroy and will render the system unusable.
