> MultipleTextOutputFormat class removed from new api. MultipleOutputs class forces developer to set names of output files at job configuration time.
> So with new api I can't create files with names based on keys (I don't know all keys. Therefore I can't set output file names at job configuration time).
> This is major disadvantage in comparison with old api and force developer to use it.
