> Key: SPARK-19807
> URL: https://issues.apache.org/jira/browse/SPARK-19807
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 2.1.0
> Reporter: Jacek Laskowski
> Assignee: Apache Spark
> Priority: Trivial

> When a user kills a stage using web UI (in Stages page), {{StagesTab.handleKillRequest}} requests {{SparkContext}} to cancel the stage without giving a reason. {{SparkContext}} has {{cancelStage(stageId: Int, reason: String)}} that Spark could use to pass the information for monitoring/debugging purposes.

> scala> sc.range(0, 5, 1, 1).mapPartitions { nums => { Thread.sleep(60 * 1000); nums } }.count
> {code}
> Use http://localhost:4040/stages/ and click Kill.
> {code}
> org.apache.spark.SparkException: Job 0 cancelled because Stage 0 was cancelled
