Alan Gates commented on PIG-878:

Should note also that I didn't add any tests because this was a fix for 
existing functionality, and frankly I'm not exactly sure how to test it.

Also should have noted thanks to Milind for first brining this to our attention.

> When SlicerWrapper builds a slice, it currently returns the 3 locations for 
> every block in the file it is slicing, instead of the 3 locations for the 
> block covered by that slice.  This means Pig's odds of having its maps placed 
> on nodes local to the data goes way down.
