> "Scheduler Delay" of a task is confusing
> ----------------------------------------
>
> Key: SPARK-23326
> URL: https://issues.apache.org/jira/browse/SPARK-23326
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 2.3.0
> Reporter: Shixiong Zhu
> Assignee: Shixiong Zhu
> Priority: Major
> Fix For: 2.3.0
>
>
> Run the following code and check the UI
> {code}
> sc.makeRDD(1 to 1, 1).foreach { i => Thread.sleep(30000) }
> {code}
> You will see "Scheduler Delay" of a task is almost the same as "Duration"
> until the task finishes. That's really confusing.
> In Spark 2.2, "Scheduler Delay" will be 0 until the task finishes. This is
> also not correct but less confusing.
