[jira] Commented: (HIVE-1072) "show table extended like table
partition(xxx) " will show the result of the whole table if the partition
does not exist
[ https://issues.apache.org/jira/browse/HIVE-1072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12803047#action_12803047 ]
Zheng Shao commented on HIVE-1072:
----------------------------------
If the partition does not exist, we should fail the query.
Can you add a negative test instead?
