Subject [jira] Created: (HADOOP-3669) Aggregate Framework should allow usage of MultipleOutputFormat

Aggregate Framework should allow usage of MultipleOutputFormat
--------------------------------------------------------------

                 Key: HADOOP-3669
                 URL: https://issues.apache.org/jira/browse/HADOOP-3669
             Project: Hadoop Core
          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.
