Subject [jira] [Created] (HIVE-6769) HCatStorer can initialize SerDe with less columns than table definition if PigSchema has less columns
Date Fri, 28 Mar 2014 00:43:14 GMT
Jason Dere created HIVE-6769:
--------------------------------

             Summary: HCatStorer can initialize SerDe with less columns than table definition
if PigSchema has less columns
                 Key: HIVE-6769
                 URL: https://issues.apache.org/jira/browse/HIVE-6769
             Project: Hive
          Issue Type: Bug
          Components: HCatalog
            Reporter: Jason Dere


You should be able to see this in TestHCatStorer.testStoreFuncAllSimpleTypes.  First a Hive
table is created with 8 columns.  Then HCatStorer is used to populate the table, but Pig relation
only has data for the first 7 columns of the table. When HCat initializes the SerDe for writing
the table, the schema only contains 7 columns rather than the 8 that the table should have.
This test works without any errors, but gets an error if the table is changed to ORC storage
(which can be fixed by HIVE-4975).

HCat should initialize the Serde with the full number of columns in the table, and should
fill in NULLs for any columns which are not provided by Pig relation.
