------------------------------------
The javac warnings are cause of deprecation markers thats happened on trunk
since the last time I did this patch:

{code}
I'll fix these shortly.

> Key: MAPREDUCE-2293
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2293
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Affects Versions: 0.21.0
> Reporter: David Rosenstrauch
> Assignee: Harsh J
> Priority: Minor
> Attachments: mapreduce.mo.removecheck.r1.diff,
> mapreduce.mo.removecheck.r2.diff, mapreduce.mo.removecheck.r3.diff,
> mapreduce.mo.removecheck.r4.diff

> Currently you are only allowed to use alpha-numeric characters in a named
> output name in the MultipleOutputs class. This is a bit of an onerous
> restriction, as it would be extremely convenient to be able to use non
> alpha-numerics in the name too. (E.g., a '.' character would be very
> helpful, so that you can use the named output name for holding a file
> name/extension. Perhaps '-' and a '_' characters as well.)
> The restriction seems to be somewhat arbitrary - it appears to be only
> enforced in the checkTokenName method. (Though I don't know if there's any
> downstream impact by loosening this restriction.)
> Would be extremely helpful/useful to have this fixed though!
