-----------------------------------
As far as I remember besides the refactoring work (committed already)
everything else are just experiments.
> Add/Remove nodes to/from running clusters

> I would like to be able to add a node to a running cluster.
> For example if I have created a hadoop, hbase, zookeeper cluster I would like
> to be able to add region servers to hbase, Zookeeper nodes to the quorum,
> and task nodes to hadoop.
> Something akin to the functionality of the hbase-ec2 script. Where if I
> launch a node on an already running cluster. It is configured to join the
> cluster.
> We should also provide hooks for removing nodes from the cluster. In many
> situations removing nodes is much harder that adding them, however this issue
> should mostly care with cloud mgmt and providing the hooks for
> addition/deletion separate issues should handle the add/remove process for
> each service, so it won't be a gargantuous task.
