             Summary: Introduce locking for container operations that are executed via DatanodeCommand
                 Key: HDDS-962
                 URL: https://issues.apache.org/jira/browse/HDDS-962
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
          Components: Ozone Datanode
            Reporter: Nanda kumar
            Assignee: Nanda kumar


When SCM decides to take some action on a container, it sends DatanodeCommand to the datanodes. These commands are handled by CommandHandlers in datanode. Without proper locking, we cannot process these commands in parallel. This jira aims to introduce locks on container operations which are performed via ContainerController.
