Doug Cutting commented on HADOOP-735:
-------------------------------------
> the generated code was catching IOException, and resulted in a compile-error

So the fix is to cause an exception to be thrown? I still don't follow. Code
which processes a buffer only is technically not doing i/o, so IOException is
also a strange one to add to these methods.
I also still don't completely see the issue. Can you provide some examples of
the generated code, or point to where in the generated test cases I might look?
Thanks.
