[jira] [Created] (HDDS-8008) Move pendingOps into ContainerStateManagerImpl to ensure consistent state

             Summary: Move pendingOps into ContainerStateManagerImpl to ensure consistent state
                 Key: HDDS-8008
                 URL: https://issues.apache.org/jira/browse/HDDS-8008
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: SCM
            Reporter: Stephen O'Donnell
            Assignee: Stephen O'Donnell


As things stand, ContainerManagerImpl holds a reference to ContainerReplicaPendingOps. As new replicas are received or deleted from the DNs, the replicas are updated in ContainerStateManager under a lock, and then pending ops is updated. This leave the possibility of a race condition where the replicas have been updated but pending ops has not.

To avoid this, we should move the pendingOps update into the StateManager so it is updated along with the replicas under the same lock.
