--------------------------------
Summary: Trigger mapstage's job listener in submitMissingTasks
Key: SPARK-23948
URL: https://issues.apache.org/jira/browse/SPARK-23948
Project: Spark
Issue Type: New Feature
Components: Spark Core
Affects Versions: 2.3.0
Reporter: jin xing
SparkContext submitted a map stage from "submitMapStage" to DAGScheduler,
"markMapStageJobAsFinished" is called only in ();
But think about below scenario:
1. stage0 and stage1 are all "ShuffleMapStage" and stage1 depends on stage0;
2. We submit stage1 by "submitMapStage", there are 10 missing tasks in stage1
3. When stage 1 running, "FetchFailed" happened, stage0 and stage1 got
resubmitted as stage0_1 and stage1_1;
4. When stage0_1 running, speculated tasks in old stage1 come as succeeded, but
stage1 is not inside "runningStages". So even though all splits(including the
speculated tasks) in stage1 succeeded, job listener in stage1 will not be
called;
5. stage0_1 finished, stage1_1 starts running. When "submitMissingTasks", there
is no missing tasks. But in current code, job listener is not triggered
