-----------------------------------
Forgot to mention this happened with impersonation enabled.
> JDBC connections cause drillbit leaks resources and eventually JVM crashes

> URL: https://issues.apache.org/jira/browse/DRILL-5150
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - JDBC
> Affects Versions: 1.9.0
> Reporter: Chun Chang
> Attachments: hs_err_pid22724.log
>
>
> Stress test JDBC connections by making connections and disconnect. Very soon,
> drillbit will crash due to resource leaks. This was observed with Apache
> DRILL JDBC driver. Testing with a third party driver did not cause the crash.
> Will upload JVM dump.
