>
> Currently the output format is hard-coded to be TextOutputFormat in 
> ValueAggregatorJob responsible for running aggregation jobs using 
> user-defined value aggregator descriptors. This prevents the application 
> writer from specifying an alternate output format.
> A good use case from an application's perspective is to have a sub-type of 
> MultipleOutputFormat set as output format which takes care of redirecting 
> (key, value)
> to different files based on type information encoded in them.
> Applications can extend MultipleTextOutputFormat and define there own 
> multiple output format but they still can't hook it into value aggregator 
> framework.
