> 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.
