> Right now streaming input is specified very differently from other map-reduce
> input. It would be good if these two apps could take much more similar input
> specs.
> In particular -input in streaming expects a file or glob pattern while MR
> takes a directory. It would be cool if both could take a glob patern of
> files and if both took a directory by default (with some patern excluded to
> allow logs, metadata and other framework output to be safely stored).
> We want to be sure that MR input is backward compatible over this change. I
> propose that a single file should be accepted as an input or a single
> directory. Globs should only match directories if the paterns is '/'
> terminated, to avoid massive inputs specified by mistake.
> Thoughts?
