Jason Dere commented on HIVE-9766:
----------------------------------
I think all of the getWritableConstantValue() methods need a if(value == null)
{ return null; }
Otherwise you risk NPE when it tries to create the writable value to return.
> Add JavaConstantXXXObjectInspector

> Need JavaConstantXXXObjectInspector when implementing PIG-3294. There are two
> approaches:
> 1. Add those classes in Pig. However, most construct of the base class
> JavaXXXObjectInspector is default scope, need to change them to protected
> 2. Add those classes in Hive
> Approach 2 should be better since those classes might be useful to Hive as
> well. Attach a patch to provide them.
