Hubert Zhang created HAWQ-1355:
----------------------------------
Summary: Namespace check may occur multiple times in first query.
Key: HAWQ-1355
URL: https://issues.apache.org/jira/browse/HAWQ-1355
Project: Apache HAWQ
Issue Type: Bug
Reporter: Hubert Zhang
Assignee: Ed Espino
When running a query, HAWQ need to check namespace usage privilege in function
recomputeNamespacePath. This function will be called repeatedly but check will
be skipped when last_query_sign is equal to current_query_sign.
There is a bug that running the first query doesn't set the last_query_sign.
