########## File path: flink-runtime/src/main/java/org/apache/flink/runtime/io/network/partition/ResultPartition.java ########## @@ -381,17 +383,20 @@ void onConsumedSubpartition(int subpartitionIndex) { return; } - int refCnt = pendingReferences.decrementAndGet(); - - if (refCnt == 0) { + if (isManagedExternally) { partitionManager.onConsumedPartition(this); Review comment: TBH I do not like the current way because it seems a bit hacky. Because during `ResultPartition#onConsumedSubpartition`, the counter would never be 0 for external case, so the `ResultPartitionManager#onConsumedPartition` would never be called, then the internal checking logic in `ResultPartitionManager#onConsumedPartition` seems reductant. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
