> 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.
