Siddharth Seth updated TEZ-646:
-------------------------------
Issue Type: Sub-task (was: Improvement)
Parent: TEZ-753
> 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: Sub-task
> Reporter: Siddharth Seth
> Assignee: Siddharth Seth
> Priority: Critical
>
> 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.
