Spark Versions failure: the legacy running, cancelled and timeout state tests called `cancel()` and returned without `waitUntilFinish()`. With the asynchronous cancel the execution thread stops the session a moment later, after the next test class in the same fork had adopted it through `SparkSessionRule` and `getOrCreate`, hence the `NullPointerException` in `registerMetricsSource` in `CombineGloballyTest`. Fixed by joining after `cancel()` in those three tests, main code unchanged. Reproduced locally on `sparkVersion35Test` (there `CombinePerKeyTest` was the victim, it started 40 ms after the state test ended in the same fork), green after the fix on Spark 3.1, 3.5 and 4. -- This is an automated message from the Apache Git Service.
