             Summary: Dropping table in an encrypted zone does not drop warehouse directory
                 Key: HIVE-10629
                 URL: https://issues.apache.org/jira/browse/HIVE-10629
             Project: Hive
          Issue Type: Sub-task
          Components: Security
            Reporter: Deepesh Khandelwal


Drop table in an encrypted zone removes the table but not its data. The client sees the following on Hive CLI:
{noformat}
hive> drop table testtbl;
OK
Time taken: 0.158 seconds
{noformat}
On the Hive Metastore log following error is thrown:
{noformat}

The client should throw the error and maybe fail the drop table call. To delete the table data one currently has to use {{drop table testtbl purge}} which basically remove the table data permanently skipping trash.
