>
> 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.
