> Issue Type: Improvement
> Affects Versions: 0.17.0
> Reporter: Ankur

>
> 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.
