----------------------------------
Resolution: Fixed
Assignee: Nishkam Ravi
Fix Version/s: 1.5.0
> Mechanism to control receiver scheduling
> -----------------------------------------
>
> Key: SPARK-7988
> URL: https://issues.apache.org/jira/browse/SPARK-7988
> Project: Spark
> Issue Type: New Feature
> Components: Streaming
> Reporter: Nishkam Ravi
> Assignee: Nishkam Ravi
> Priority: Critical
> Fix For: 1.5.0
>
>
> Streaming receivers are currently scheduled by the underlying Spark scheduler
> in the same way as other tasks. Will help performance if we added a knob to
> control receiver scheduling. In most cases, even distribution of receivers
> among workers should yield best results. In some cases, dense scheduling
> (e.g, all receivers on one node) may perform better. Maybe support for a new
> configuration parameter spark.receiver.scheduling.mode (or some such) would
> help. With 'default' as the current scheduling scheme and 'round-robin' for
> even distribution among workers (and potentially a third mode for 'dense'
> scheduling).
