Subject [jira] [Commented] (HIVE-3678) Add metastore upgrade scripts for column stats schema changes
Date Mon, 19 Nov 2012 20:11:59 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13500599#comment-13500599

Ashutosh Chauhan commented on HIVE-3678:
----------------------------------------

I agree with Carl, making it easier to evolve such that its independent of exact type will
be a win. We already have one such use-case with BigDecimal support being added over on HIVE-2693.


Also, following looks unintentional change.
{code}
 -- Constraints for table PARTITION_KEYS
-ALTER TABLE PARTITION_KEYS ADD CONSTRAINT PARTITION_KEYS_FK1 FOREIGN KEY (TBL_ID) REFERENCES
TBLS (TBL_ID) INITIALLY DEFERRED ;
+ALTER TABLE PARTITION_KEYS ADD CONSTRAINT PARTITION_KEYS_FK1 FOREIGN KEY (TBTB_ID) REFERENCES
TBLS (TBL_ID) INITIALLY DEFERRED ;
{code}
