Hi, All. This is a kind of head-up as a part of Apache Spark 4.0.0 preparation.
https://issues.apache.org/jira/browse/SPARK-44111 (Prepare Apache Spark 4.0.0) It would be great if we are able to fix long-standing `Spark Connect` test flakiness together during the QA period (2025-02-01 ~) in order to make sure that we didn't miss any bugs here. SPARK-48139: Re-enable `SparkSessionE2ESuite.interrupt tag` SPARK-50205: Re-enable `SparkSessionJobTaggingAndCancellationSuite.Cancellation APIs in SparkSession are isolated` SPARK-50748: Fix a flaky test: `SparkSessionE2ESuite.interrupt all - background queries, foreground interrupt` SPARK-50888: Fix Flaky Test: `SparkConnectServiceSuite.SPARK-44776: LocalTableScanExe` SPARK-50889: Fix Flaky Test: `SparkSessionE2ESuite.interrupt operation` (Hang) Since many people consider the `Spark Connect` module important, some of JIRA issues are marked as `Blocker` priority for 4.0.0 currently. So, I hope we can make them re-enabled and stable to be safe. However, we can also simply remove `Blocker` status before RC1 (2025-02-15) and ignore all of those test cases if `Spark Connect` module experts are sure that there are no `Spark Connect` functional issues behind these. In this case, the above issues will be re-scoped to Spark 4.1.0 as `Minor` priorities. Sincerely, Dongjoon.
