> 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.
