Tom White commented on WHIRR-214:
---------------------------------
The refactoring patch looks good, although I don't see the addInstance() method
being used anywhere (even in the other patch).
Would "repair" be better named "converge", since it covers both cases of
repairing a cluster where some of the instances didn't come up, and extending a
cluster to a larger size. We could add shrinking a cluster sometime, but for
the moment it should throw an exception.
The patch contains a default for the tarball URL, which would be better put in
a properties file.

> 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.
