             Summary: Unnecessary entries created in ZK when a jdbc application uses a wrong connection URL 
                 Key: DRILL-4433
                 URL: https://issues.apache.org/jira/browse/DRILL-4433
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - JDBC
            Reporter: Rahul Challapalli


commit # : 6d5f4983003b8f5d351adcb0bc9881d2dc4c2d3f
commit date : Feb 22, 2016

In my JDBC application, I accidentally used an invalid connection string like below
{code}
jdbc:drill:zk=x.x.x.x:5181/zkroot-blah/cluster-name
{code}
While drill correctly reported an "No DrillbitEndpoint can be found error", I also observed that it created an entry in zookeeper by the name "zkroot-blah". There seems to be no reason for doing this.
