Subject [jira] [Created] (HDDS-709) Modify Close Container handling sequence on datanodes
Date Mon, 22 Oct 2018 11:31:00 GMT
Shashikant Banerjee created HDDS-709:
----------------------------------------

             Summary: Modify Close Container handling sequence on datanodes
                 Key: HDDS-709
                 URL: https://issues.apache.org/jira/browse/HDDS-709
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
            Reporter: Shashikant Banerjee
            Assignee: Shashikant Banerjee


With quasi closed container state for handling majority node failures, the close container
handling sequence in Datanodes need to change. Once the datanodes receive a close container
command from SCM, the open container replicas individually be marked in the closing state.
In a closing state, only the transactions coming from the Ratis leaderĀ  are allowed , all
other write transaction will fail. A close container transaction will be queued via Ratis
on the leader which will be replayed to the followers which makes it transition to CLOSED/QUASI
CLOSED state.
