------------------------------

    Attachment: zookeeper-repair-or-extend-cluster.patch

Attached a proof-of-concept implementation that adds a new command (repair-cluster) which can be used to repair or extend a ZooKeeper cluster with small downtime (reconfig + restart) and no data loss.

> 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.
