             Summary: Avoid creating multiple copies of the same Event payload
                 Key: TEZ-646
                 URL: https://issues.apache.org/jira/browse/TEZ-646
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


OnFileSortedOutput generates the same event payload for all downstream tasks. As an example, for a simple MR job - the number of copies of this is equal to the number of reduce tasks.

This needs to be done in a clean manner though - since the event model is meant to generate a separate payload for each downstream task.
