How to add nodes to existing cluster?
I am trying to add nodes to an existing working cluster. Do I need to bring
the entire cluster down or just shutting down and restarting the namenode
after adding the new machine list to the slaves would work?

If you want them to also start automatically, and for the slaves.sh command
to work as expected, add the names to the conf/slaves file also.

Just starting DataNode and TaskTracker would add it to cluster.
