Sean Busbey commented on ACCUMULO-1421:
---------------------------------------
A compatibility layer would be a great idea. It also gives some room for
dealing with future incompatibilities. Hive (HIVE-3029) does this, and Pig
(PIG-2686) used to. Probably a package, as Hive does, would be best.
I think pushing for trunk is prudent, since the pressure to get 1.5 out is high
and there's uncertainty on how wide a change this needs.

> JobContext switches between an abstract class and an interface in hadoop 1
> and 2, causing runtime compatibility problems in the compiled Accumulo
> bytecode. Avoid the runtime problem by using reflection to access the
> configuration object stored in the JobContext.
