Olga Natkovich commented on PIG-1518:
-------------------------------------
Hi Justin, thanks for the patch!
I don't think we can commit it to 0.7 patch because we have already done the
official 0.7 release and we can't introduce non-backward compatible changes to
this branch.
However, I think it is great to have the patch on the JIRA so that anybody who
is interested in this patch can apply it to their own tree and run with it. We
have done similar things in the past (with hadoop versions) and it worked fine.

> We frequently run in the situation where Pig needs to deal with small files
> in the input. In this case a separate map is created for each file which
> could be very inefficient.
> It would be greate to have an umbrella input format that can take multiple
> files and use them in a single split. We would like to see this working with
> different data formats if possible.
> There are already a couple of input formats doing similar thing:
> MultifileInputFormat as well as CombinedInputFormat; howevere, neither works
> with ne Hadoop 20 API.
> We at least want to do a feasibility study for Pig 0.8.0.
