Description

I recently put in MAPREDUCE-4503 which went a bit too far, and broke backwards compatibility with 1.0 in distribtued cache entries. instead of changing the behavior of the distributed cache to more closely match 1.0 behavior I want to just change the exception to a warning message informing the users that it will become an error in 2.0
