             Summary: Ozone: Add datanodeID to heartbeat responses and 
container protocol
                 Key: HDFS-12756
                 URL: https://issues.apache.org/jira/browse/HDFS-12756
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Anu Engineer
            Assignee: Anu Engineer


if we have datanode ID in the HBs responses and commands send to datanode, we 
will be able to do additional sanity checking on datanode before executing the 
command. This is also very helpful in creating a MiniOzoneCluster with 1000s of 
simulated nodes. This is needed for scale based unit tests of SCM.
