Minor Changes to SliceWrapper for Generic Hadoop InputFormat
------------------------------------------------------------

                 Key: PIG-300
                 URL: https://issues.apache.org/jira/browse/PIG-300
             Project: Pig
          Issue Type: Improvement
         Environment: trunk
            Reporter: Christian Kunz


I am working on a Load Function that allows to specify any Hadoop FileInputFormat or CompositeInputFormat.

Because of the nature of PigSlice and PigSlicer such a UDF needs to use a different implementation
of Slice and Slicer.

It turns out that it would be extremely helpful if the SliceWrapper class had a couple of
minor changes:

1) an additional get method to return the 'wrapped' slice.
2) change to getLocations method to just call the getLocations() method of the wrapped Slice,
unless 'wrapped' is a PigSlice (in which case it just does what it does now).

I will make a patch available shortly.
