----------------------------------------------------------------

bq. I didn't call out on this (stability aspect?). Unsure why you're exclaiming 
it, thats all 
Exclamation was to indicate that this a very old change and not the stability 
aspect. 

bq. We have a release out there we aren't yet encouraging adoption upon, which 
has all this in it already.
Not sure I understand. In case you are talking about 0.21, you know the status 
of that as well as 0.22.

bq. are we also intending to do the DistCp optimizations that can benefit from 
this, i.e. MAPREDUCE-2117 and MAPREDUCE-2557, so that there's also an internal 
use of this, out of the box
Right now I was not planning to. I encourage you to port it to 1.0, if you 
think the users benefit from it.

> single file. This helps several use cases where writes can be parallelized 
> and several folks have expressed in this functionality.
