I need to output 3 different XML files from my map reduce job. I currently have it working for a single file, but when I try to add in the logic for MultipleOutputs to the reducer to support splitting the files, I get errors from the writer attempting to write to the same file. I assume thats caused by trying to manage the output file name via the custom FileOutputFormat class implementation.
Has anyone got a good example of combining MultipleOutputs and a custom OutputFormat class that I can use? To make matters worse I have to configure all of this via Oozie as thats enforced by the commercial Hadoop appliance my company uses.
