-------------------------------
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.
