> Step 2 collects necessary host assignment information from the user (which host to place
the second NameNode and 3 JournalNodes).
> Ask the user which hosts to map NN2 and 3 JNs.  For the user’s info, we show where
the existing NN is as well.
> “Select a host that will be running an additional NameNode.  In addition, select 3
hosts that will be running JournalNodes to store NameNode edit logs in a fault tolerant manner.”
