> Add Receiver scheduling info onto Spark Streaming web UI
> --------------------------------------------------------
>
> Key: SPARK-12305
> URL: https://issues.apache.org/jira/browse/SPARK-12305
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.5.2
> Reporter: Liwei Lin
> Priority: Minor
>
> Spark 1.5 has added better Receiver scheduling support, via which users can
> deploy Receivers to certain Executors in a way they wish.
> However, neither 'Receiver.preferredLocations' info nor the candidate
> Executors info are displayed on the web UI. Then when Receivers are not
> scheduled in the way users have specified, it's non-trivial for the users to
> find out why.
> This issue proposes to add Receiver scheduling info, including
> 'Receiver.preferredLocations' info as well as the candidate Executors info,
> onto Spark Streaming web UI.
