> MAPREDUCE-898 moved distributed cache setters and getters into Job and JobContext.  Since
the API is new, I'd like to propose that those getters never return null, but instead always
return an array, even if it's empty.
> If people don't like this change, I can instead merely update the javadoc to reflect
the fact that null may be returned.
