> [This build|https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=42011&view=logs&j=77a9d8e1-d610-59b3-fc2a-4766541e0e33&t=125e07e7-8de0-5c6c-a541-a567415af3ef&l=8433] failed (not exclusively) due to {{SortMergeResultPartitionReadSchedulerTest.testCreateSubpartitionReader}}. The assert checking that the {{SortedMergeSubpartitionReader}} is in running state fails.
> My suspicion is that the condition in [SortMergeResultPartitionReadScheduler.mayTriggerReading|https://github.com/apache/flink/blob/87d4f70e49255b551d0106117978b1aa0747358c/flink-runtime/src/main/java/org/apache/flink/runtime/io/network/partition/SortMergeResultPartitionReadScheduler.java#L425-L428] (or something related to that condition) needs to be reconsidered since that's the only time {{isRunning}} is actually set to true.
