             Summary: Generate BlockCommitSequenceId in ContainerStateMachine for every commit operation in Ratis Leader
                 Key: HDDS-450
                 URL: https://issues.apache.org/jira/browse/HDDS-450
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
            Reporter: Shashikant Banerjee
            Assignee: Shashikant Banerjee


BlockCommitSequenceId will be monotonically increasing long value generated in the Ratis leader for every commit operation of a block and will be replicated over to the followers. This id will be updated in OM and will be reported to SCM which will help the most consistent copy of a open container replica in case the majority of the datanodes fail .
