Hitesh Shah commented on TEZ-2636:
----------------------------------
Patch seems fine.
General comment on MRInput ( unrelated to patch to some extent ):
- if the input is to be initialized via events, why is
"getContext().inputIsReady();" being invoked even before the input has received
the event? Should it not be the case that isReady() should only be done if
input count is 0 or if input initialized from splits in dist cache?
> MRInput and MultiMRInput should work for cases when there are 0 physical
> inputs

> It's possible that an Input is setup without any actual data. This is
> especially valid when a task is processing multiple MRInputs. One side has
> data, but the other does not. In such cases - we currently end up generating
> an error.
