Subject [jira] [Updated] (HIVE-3964) HIVE-3649.oracle.sql must update SDS table for IS_STOREDASSUBDIRECTORIES
Date Wed, 13 Mar 2013 20:24:12 GMT

     [ https://issues.apache.org/jira/browse/HIVE-3964?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mithun Radhakrishnan updated HIVE-3964:
---------------------------------------

    Description: 
The metastore-update script is available now on branch-0.10. (As part of HIVE-3931.)

However, the 011-HIVE-3649.oracle.sql script (that updates the SDS table) introduces a non-NULL
constraint on a new field (that doesn't exist in the old schema). The correct way to update
the SDS table is as it's done in trunk: 

{{ALTER TABLE  SDS ADD IS_STOREDASSUBDIRECTORIES NUMBER(1) NULL;
UPDATE SDS SET IS_STOREDASSUBDIRECTORIES = 0;
ALTER TABLE SDS MODIFY(IS_STOREDASSUBDIRECTORIES NOT NULL);}}


  was:
upgrade-0.9.0-0.10.0.oracle.sql isn't available in metastore/scripts/upgrade/oracle. 

This warrants testing as well. My concern is that SDS::IS_STOREDASSUBDIRECTORIES is a new,
non-nullable column. Existing rows in SDS might need updating with a "default" value (0) before
the constraint is applied.

I'll post a patch shortly.
