########## File path: flink-runtime/src/main/java/org/apache/flink/runtime/jobmaster/slotpool/SlotSharingManager.java ########## @@ -612,7 +612,9 @@ private void releaseChild(AbstractID childGroupId) { TaskSlot child = children.remove(childGroupId); if (child != null) { - allTaskSlots.remove(child.getSlotRequestId()); + if (child == allTaskSlots.get(child.getSlotRequestId())) { + allTaskSlots.remove(child.getSlotRequestId()); + } Review comment: I would actually make this a precondition in the master branch because the original problem occurred because we were reusing `SlotRequestIds` which were never intended for this purpose. In the `release-1.9` branch, we can keep it like it is. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
