Martin Traverso commented on HADOOP-2906:
-----------------------------------------
I would suggest changing the name of the property from
"num.of.trailing.legs.to.use" to something that reflects the hierarchy in which
the property lives. Maybe something like
mapred.output.format.multi.trailingLegs or similar.
> output format classes that can write to different files depending on keys
> and/or config variable

> I've a few apps that require to write out data into different
> files/directories depending on keys and/or configuration variables.
> I've implemented such classes for those apps. I noticed that many other users
> have similar need from time to time.
> So I think it may be a good idea to contribute to Hadoop mapred.lib package
> so that other users can benefit from it.
