> The Install Wizard starts the Datanode before starting the other HDFS components. This
means that "hdfs dfsadmin -report -live" should only be called from the Restart of a Rolling
Upgrade, instead of a normal Restart.
> Rolling Upgrades will need a mechanism to perform pre-restart and post-restart hooks
depending on the parameters passed to the Restart action.
