Subject [jira] [Created] (HDDS-197) DataNode should return Datanode to return ContainerClosingException/ContainerClosedException (CCE) to client if the container is in Closing/Closed State

Shashikant Banerjee created HDDS-197:
----------------------------------------

             Summary: DataNode should return Datanode to return ContainerClosingException/ContainerClosedException
(CCE) to client if the container is in Closing/Closed State
                 Key: HDDS-197
                 URL: https://issues.apache.org/jira/browse/HDDS-197
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Client, Ozone Datanode
            Reporter: Shashikant Banerjee
            Assignee: Shashikant Banerjee
             Fix For: 0.2.1


SCM queues the CloeContainer command to DataNode over herabeat response which is handled by
the Ratis Server inside the Datanode. In Case, the container transitions to CLOSING/CLOSED
state, while the ozone client is writing Data, It should throw ContainerClosingException/ContainerClosedExceptionContainerClosingException/ContainerClosedException
accordingly. These exceptions will be handled by the client which will retry to get the last
committed BlockInfo from Datanode and update the OzoneMaster.
