########## File path: flink-runtime/src/main/java/org/apache/flink/runtime/resourcemanager/slotmanager/SlotManagerImpl.java ########## @@ -125,20 +126,29 @@ * */ private boolean failUnfulfillableRequest = true; + /** + * The default resource spec of workers to request.

I think this would also better reflect that the `SlotManagerImpl` does not really care whether it's running in a Standalone- or YarnResourceManager. At the moment, the `SlotManagerImpl` contains code which behaves differently depending on whether this field is null or not. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
