Scala Hadoop Enrich: added test for empty integer and double fields to ensure no NPE thrown (#1063)
@yalisassoon - I've added the test and improved the null handling for integers and doubles (see previous commits). The odd thing is that the improved null handling seems somehow orthogonal to this test case. You can see from the validation errors that both of the missing fields were processed as empty strings, not nulls. It's odd. I think something must have changed between Hadoop 0.6.0 and 0.8.0 (this release) to prevent the NPE issues. I have done some deep digging and can't figure out what, but it looks like the problem is gone. Software huh?
