MAHOUT-457: ItemSimilarityJob and RecommenderJob don't work on Amazon

>
> I'm currently evaluating ItemSimilarityJob and RecommenderJob on
> ElasticMapReduce, it seems we have some small problems with S3, mostly due to
> the fact that we need to use Filesystem.get(path.toUri(), conf) instead of
> Filesystem.get(conf) in the code. I will create a patch for that the next
> days.
> I'm writing this mail because I encountered another problem I currently can't
> solve. RecommenderJob is emulating MultipleInputs (which is currently missing
> in Hadoop 0.20 AFAIK) by reading data from a combined path that is built like
> that:
> new Path(prePartialMultiplyPath1 + "," + prePartialMultiplyPath2)
> My Job always fails with this exception here:
> java.lang.IllegalArgumentException: Invalid hostname in URI
> s3:/testingbucket-12345/tmp/prePartialMultiply2
