> Two test case classes {{TestJdbcQuery}} and {{TestJdbcDistQuery}} both call
> {{org.apache.drill.exec.store.hive.HiveTestDataGenerator.generateTestData()}} during the test phase which starts with cleaning up of scratch directory.
> {noformat}
>   public void generateTestData() throws Exception {
>     // remove data from previous runs.
>     cleanDir(DB_DIR);
>     cleanDir(WH_DIR);
> ...
> {noformat}
> However the files opened by the first tests are not closed before the second test starts execution and hence the execution fails.

> A fix for this would require shutting down the Hive service(s) (Metastore?) between the test runs.
