[SPARK-24415][CORE] Fixed the aggregated stage metrics by retaining stage objects in liveStages until all tasks are complete The problem occurs because stage object is removed from liveStages in AppStatusListener onStageCompletion. Because of this any onTaskEnd event received after onStageCompletion event do not update stage metrics. The fix is to retain stage objects in liveStages until all tasks are complete. 1. Fixed the reproducible example posted in the JIRA 2. Added unit test Closes #22209 from ankuriitg/ankurgupta/SPARK-24415.
