David Alves commented on WHIRR-214:
-----------------------------------
My suggestion would be to make the focus of this issue the non-service-specific
part of expansion and contraction and to define hooks that specific services
can use to handle adding and removing nodes from a running cluster, which as
Tom said can be tricky in a series of cases.

> 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.
