             Summary: Drill may leak hive meta store connection if hive meta store client call hits error
                 Key: DRILL-4768
                 URL: https://issues.apache.org/jira/browse/DRILL-4768
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Jinfeng Ni


We are seeing one drillbit creates hundreds of connections to hive meta store. This indicates that drill is leaking those connection, and did not close those connections properly. When such leaking happens, it may prevent other applications from connecting to hive meta store. 

It seems one cause of leaking connection happens when hive meta store client call hits exception.
