             Summary: Add functionality to construct OpenContainerBlockMap on datanode restart
                 Key: HDDS-306
                 URL: https://issues.apache.org/jira/browse/HDDS-306
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
            Reporter: Shashikant Banerjee
            Assignee: Shashikant Banerjee
             Fix For: 0.2.1


OpenContainerBlockMap contains list of blocks which are not committed on a Datanode. In case the Datanode restarts, we may need to reconstruct this map by reading block layout for each container and verifying it with the container DB. This is required to close the container on a single dataNode as well as for Ozone garbage collection
