Subject [jira] [Created] (HIVE-5366) Refactor a few object inspector class to eliminate redundant information
Date Thu, 26 Sep 2013 02:15:02 GMT
Xuefu Zhang created HIVE-5366:
---------------------------------

             Summary: Refactor a few object inspector class to eliminate redundant information
                 Key: HIVE-5366
                 URL: https://issues.apache.org/jira/browse/HIVE-5366
             Project: Hive
          Issue Type: Improvement
          Components: Serializers/Deserializers, Types
    Affects Versions: 0.12.0
            Reporter: Xuefu Zhang
            Assignee: Xuefu Zhang
             Fix For: 0.13.0


AbstractPrimitiveObjectInspector class has two fields:

{code}
  protected PrimitiveTypeEntry typeEntry;
  protected BaseTypeParams typeParams;
{code}

But PrimitiveTypeEntry already has member BaseTypeParams instance, which is identical to "typeParams"
we see here. Thus, there is some redundant information stored at different places. Ideally,
we should have a single point of truth.

This refactoring is required by HIVE-3976 work. This is singled out to make the review easier.
