> 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.
