Adrian Cole commented on WHIRR-214:
-----------------------------------
one way to resize a cluster based on a current one is to persist the "template"
of the cluster onto one of the machines (or all of the machines). Ex.
serialize the template to json and copy it to disk. When going to resize the
cluster, pick any member and the deserialize the template from this location.
ex. put(".template", Payloads.newStringPayload(json.asJson(template)))
make sense?

> 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.
