[jira] [Comment Edited] (SPARK-20205) DAGScheduler posts
SparkListenerStageSubmitted before updating stage
[ https://issues.apache.org/jira/browse/SPARK-20205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15954387#comment-15954387 ]

For history server that will fail - good point.
Atleast for custom listeners, users can workaround until next release by using current time (in there code when field submissionTime is None).
Thanks for clarifying [~vanzin] !

> Key: SPARK-20205
> URL: https://issues.apache.org/jira/browse/SPARK-20205
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.2.0
> Reporter: Marcelo Vanzin
>
> Probably affects other versions, haven't checked.
> The code that submits the event to the bus is around line 991:
> {code}
> stage.makeNewStageAttempt(partitionsToCompute.size, taskIdToLocations.values.toSeq)
> listenerBus.post(SparkListenerStageSubmitted(stage.latestInfo, properties))
> {code}
> Later in the same method, the stage information is updated (around line 1057):
> {code}
> if (tasks.size > 0) {
> logInfo(s"Submitting ${tasks.size} missing tasks from $stage (${stage.rdd}) (first 15 " +
> s"tasks are for partitions ${tasks.take(15).map(_.partitionId)})")
> taskScheduler.submitTasks(new TaskSet(
> tasks.toArray, stage.id, stage.latestInfo.attemptId, jobId, properties))
> stage.latestInfo.submissionTime = Some(clock.getTimeMillis())
> {code}
> That means an event handler might get a stage submitted event with an unset submission time.
