What versions of hbase? The 'exception' is INFO level -- not WARN or ERROR -- coming up out of zookeeper. When does it happen? When you shut down your client? Close up of zk client connection can be a little awkward. This note from 0.90.0RC2 javadoc says a little on whats going on: http://people.apache.org/~stack/hbase-0.90.0-candidate-2/docs/apidocs/org/apache/hadoop/hbase/client/HConnectionManager.html
