             Summary: Ozone: SCM : Add priority for datanode commands
                 Key: HDFS-11715
                 URL: https://issues.apache.org/jira/browse/HDFS-11715
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: ozone
            Reporter: Anu Engineer
            Assignee: Anu Engineer


While reviewing HDFS-11493, [~cheersyang] commented that it would be a good idea to support priority for datanode commands send from SCM.

bq. The queue seems to be time ordered, I think it will be better to support priority as well. Commands may have different priority, for example, replicate a container priority is usually higher than delete a container replica; replicate a container also may have different priorities according to the number of replicas 

This jira tracks that work item.
