--------------------------------------

             Summary: DAGScheduler posts SparkListenerStageSubmitted before updating stage
                 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.
