> Use loopback for minizkcluster.  HBASE-23919 shows how sometimes unit tests fail in setup because the minizkcluster won't come up. It looks like client is trying to stat the server but though the server is trying to poll a socket bound to 0.0.0.0, the server never notices the client pings. Using loopback, I don't see these odd failures anymore.
