Small nitpick below.


    Is this looking for a single space?  Commit instead with a regex that looks for all white-space.

> HBASE-2694 did a good bit of reworking around ZK, and removed/changed some pieces that
were needed for replication to work correctly. Mainly 2 things:
>  - listZnodes needs to offer a version that takes a Watcher, else registering yourself
as a listener is too much of a pain since you then filter a lot of stuff based on the path
of the event/
>  - A lot more important, the new Multiton implemented in ZKW prevents from starting multiple
clusters inside the same JVM since both masters would use the same "name".
> I will provide a patch for both issues.
