Apache Spark reassigned SPARK-33016: ------------------------------------ Assignee: (was: Apache Spark) > Potential SQLMetrics missed which might cause WEB UI display issue while AQE > is on. > ----------------------------------------------------------------------------------- > > Key: SPARK-33016 > URL: https://issues.apache.org/jira/browse/SPARK-33016 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.0.0 > Reporter: Leanken.Lin > Priority: Minor > > In current AQE execution, there might be a following scenario which might > cause SQLMetrics being incorrectly override. > # Stage A and B are created, and UI updated thru event > onAdaptiveExecutionUpdate. > # Stage A and B are running. Subquery in stage A keep updating metrics thru > event onAdaptiveSQLMetricUpdate. > # Stage B completes, while stage A's subquery is still running, updating > metrics. > # Completion of stage B triggers new stage creation and UI update thru event > onAdaptiveExecutionUpdate again (just like step 1). > > But it's very hard to re-produce this issue, since it was only happened with > high concurrency. For the fix, I suggested that we might be able to keep all > duplicated metrics instead of updating it every time. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
