I’ve got MultipleOutputs configured to generate 2 named outputs. I’d like to send one to s3n:// and one to hdfs://
Is this possible?

This is not currently possible to do with the available API.
The
MultipleOutputsclass if Hadoop MapReduce currently works only for sub-directory (of the configured output directory) output names, which lets it take care of the side-effects caused by speculative execution.However, you could re-implement the class (or derive from it), to support this as its not impossible to achieve. You may need a more complex OutputCommitter implementation as well, if you plan on making your implementation support speculative execution.
