Subject [jira] [Commented] (HIVE-2484) Enable ALTER TABLE SET SERDE to work on partition level
Date Thu, 06 Oct 2011 05:04:29 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13121722#comment-13121722

He Yongqiang commented on HIVE-2484:
------------------------------------

I haven't looked at partition's object to see if there is a method there. But technically,
the partition's columns are copied from tables right now. So after a table's columns got changes,
the old partitions can still have old ones, though they are not used today.
