> This bug was introduced via HBASE-6677 "Random ZooKeeper port in test can overrun max port".
> If 2181 is occupied but you start a LocalHBaseCluster (let's say you untar hbase and start it right away) you'll get this:

> The reason is that MiniZookeeperCluster.selectClientPort returns 2181 if defaultClientPort is greater than 0, which it always is when starting a LocalHBaseCluster.
