Subject [jira] Commented: (HIVE-109) 'location' clause for table creation should only be allowed for external tables
Date Fri, 11 Sep 2009 21:51:57 GMT

    [ https://issues.apache.org/jira/browse/HIVE-109?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12754371#action_12754371

Prasad Chakka commented on HIVE-109:
------------------------------------

I think there are quite a few people who use this feature and those usecases will break by
fixing this. But I don't see any problem here, if users don't want their data to be deleted
with the table they can use EXTERNAL flag otherwise they will not use it. It does not matter
whether 'location' has been specified or not.

> currently - the code does not by and large distinguish between external and internal
tables. one clear distinction though is that storage for external tables is managed outside
hive. this leads to consequences like HIVE-86 - so that hive does not mess around with tables
whose storage is managed externally. however - currently - we allow users to specify location
for internal tables - which is confusing and could lead to data being deleted in external
folders. we should not allow this.
