########## File path: flink-runtime/src/main/java/org/apache/flink/runtime/resourcemanager/ResourceManager.java ########## @@ -185,6 +199,10 @@ public ResourceManager( this.jmResourceIdRegistrations = new HashMap<>(4); this.taskExecutors = new HashMap<>(8); this.taskExecutorGatewayFutures = new HashMap<>(8); + + this.defaultTaskManagerMemoryMB = ConfigurationUtils.getTaskManagerHeapMemory(flinkConfig).getMebiBytes(); + this.numberOfTaskSlots = flinkConfig.getInteger(TaskManagerOptions.NUM_TASK_SLOTS); + this.slotsPerWorker = updateTaskManagerConfigAndCreateWorkerSlotProfiles(this.flinkConfig, defaultTaskManagerMemoryMB, numberOfTaskSlots); Review comment: Yes, the background of this calculating `slotsPerWorker` on RM is that, we need to know the resource profiles of slots for `PendingTaskManagerSlot` before TM is started and registered. For standalone, we don't have any pending task manager slot because RM cannot actively start any TM. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
