Multiple mappers join into reducer
----------------------------------
Key: HADOOP-3072
URL: https://issues.apache.org/jira/browse/HADOOP-3072
Project: Hadoop Core
Issue Type: New Feature
Components: mapred
Reporter: Yiping Han
We would like to have multiple different mappers that takes input from
different locations and output records with the same format. So the output of
the mappers could be joint in the reducer easily. We know this can be achieved
in the current framework. But the way to achieve it is not natural, less
flexibility (need code change). Thus this would be a convenient feature to
have.
