SPARK-965: https://spark-project.atlassian.net/browse/SPARK-965 SPARK-966: https://spark-project.atlassian.net/browse/SPARK-966 * Add back DAGScheduler.start(), eventProcessActor is created and started here. Notice that function is only called by SparkContext. * Cancel the scheduled stage resubmission task when stopping eventProcessActor * Add a new DAGSchedulerEvent ResubmitFailedStages This event message is sent by the scheduled stage resubmission task to eventProcessActor. In this way, DAGScheduler.resubmitFailedStages is guaranteed to be executed from the same thread that runs DAGScheduler.processEvent. Please refer to discussion in SPARK-966 for details. |
