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.
