Bikas Saha updated TEZ-806:
---------------------------
Issue Type: Sub-task (was: Bug)
Parent: TEZ-803
> Ensure appropriate number of data movement events are generated by a task
> -------------------------------------------------------------------------
>
> Key: TEZ-806
> URL: https://issues.apache.org/jira/browse/TEZ-806
> Project: Apache Tez
> Issue Type: Sub-task
> Reporter: Bikas Saha
>
> For every outgoing edge of a vertex, tasks need to produce data movement
> events for consumers. If a task does not produce a data movement event then
> the job will hang since the consumer task will be stuck waiting for input.
> Additionally, if possible, we should check that the appropriate number of
> events have been produced. This may need enhancements to the edge manager API
> for custom edges.
