      Description

      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.
