########## File path: core/src/main/scala/org/apache/spark/scheduler/TaskScheduler.scala ########## @@ -109,4 +109,13 @@ private[spark] trait TaskScheduler { */ def applicationAttemptId(): Option[String] + /** + * SPARK-25250: Whenever any Task gets successfully completed, we simply mark the + * corresponding partition id as completed in all attempts for that particular stage and + * additionally, for a Result Stage, we also kill the remaining task attempts running on the + * same partition.

Review comment: I wouldn't mention the TaskCommitDenied bit here -- that's really just one very particular thing which can go wrong later. Also I think its worth mentioning that this method must be called from inside the DAGScheduler event loop, to ensure a consistent view of all task sets for the given stage. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
