--------------------------------
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.
