how to specify MultipleOutputs, MultipleInputs in using Avro mapred API

[ey-chih chow]

Hi,
I got a Map/Reduce job that require multiple inputs and outputs.  One of the 
inputs will be processed by a mapper and a reducer that are subclasses of 
AvroMapper/AvroReducer respectively.  And the reducer has multiple outputs.  I 
appreciate if anybody could let me know how to configure the job to do this.
