> Stage retry causes totalRunningTasks calculation to be negative
> ---------------------------------------------------------------
>
> Key: SPARK-27630
> URL: https://issues.apache.org/jira/browse/SPARK-27630
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: dzcxzl
> Assignee: dzcxzl
> Priority: Minor
> Labels: release-notes
> Fix For: 3.0.0
>
>
> Track tasks separately for each stage attempt (instead of tracking by stage),
> and do NOT reset the numRunningTasks to 0 on StageCompleted.
> In the case of stage retry, the {{taskEnd}} event from the zombie stage
> sometimes makes the number of {{totalRunningTasks}} negative, which will
> causes the job to get stuck.
> Similar problem also exists with {{stageIdToTaskIndices}} &
> {{stageIdToSpeculativeTaskIndices}}.
> If it is a failed {{taskEnd}} event of the zombie stage, this will cause
> {{stageIdToTaskIndices}} or {{stageIdToSpeculativeTaskIndices}} to remove the
> task index of the active stage, and the number of {{totalPendingTasks}} will
> increase unexpectedly.
