Concise error message when attempting to connect to ZK on the wrong port
------------------------------------------------------------------------
Key: HBASE-2715
URL: https://issues.apache.org/jira/browse/HBASE-2715
Project: HBase
Issue Type: Improvement
Components: zookeeper
Reporter: Jeff Hammerbacher
If we try to connect to ZK running on the wrong port, we generate a lot of
spew: http://gist.github.com/434943. It would be good to catch this case and
suggest to the user why things may have gone wrong (e.g. you've tried to
connect to the wrong port for ZK) and how to check if ZK is actually running on
that port (e.g. {{echo 'ruok' | nc localhost 2181}})
