Karthik Kambatla commented on MAPREDUCE-5063:
---------------------------------------------
While it is an interesting ask, I am not sure changing the PL semantics and
guarantees of MapReduce is a good idea. Please share a design doc if you have a
particular approach in mind. If we can continue to support the same
semantics/guarantees we have been so far with the proposed changes, may be we
can include it?
