single zk node buckling under small node?  connections never timing out?

                 Key: HBASE-1614
                 URL: https://issues.apache.org/jira/browse/HBASE-1614
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: stack
             Fix For: 0.20.0


A few (Irfan on the list and jgray) report that a single node zk seems 
insufficient supporting small cluster < 20 nodes.  This seems odd (though, 
yeah, we're recommending serious deploys must have a quorum of >= 3 zk nodes).  
Also, reports that all connections fill up and don't time out though job is 
done (on IRC).  Take a look.

(Check zk stat to see if it'll dump connections)
