Bikas Saha commented on TEZ-1168:
---------------------------------
Can you please describe the flow for the SMB case. Its hard to understand
without that context and look at the changes from a logical point of view. I
would expect each input on the task (that points to one member of the SMB join)
to be an MRInput.

> A logical Input which can process multiple splits, and gives back a reader
> for each of them.
> Used by SMB joins in Hive - which have multiple sorted files, which need to
> be merged together.
