[jira] [Created] (HAWQ-1551) issue on DROP TABLE when the table is altering by other session

Kuien Liu created HAWQ-1551:
-------------------------------

             Summary: issue on DROP TABLE when the table is altering by other session
                 Key: HAWQ-1551
                 URL: https://issues.apache.org/jira/browse/HAWQ-1551
             Project: Apache HAWQ
          Issue Type: Bug
          Components: DDL
            Reporter: Kuien Liu
            Assignee: Radar Lei


DROP TABLE should look up relation name/id again after it obtains locks, because other sessions may change the table concurrently.

GPDB has confirmed this issue, I think, Hawq may suffer from it as well.
