Yangze Guo created FLINK-20837: ---------------------------------- Summary: Assign an increasing number larger than the numberOfSlot to dynamic slots Key: FLINK-20837 URL: https://issues.apache.org/jira/browse/FLINK-20837 Project: Flink Issue Type: Sub-task Reporter: Yangze Guo Fix For: 1.13.0
In FLINK-14189, we specified that the SlotID whose slot number is -1 represents the dynamic slot. However, the SlotID with a negative slot number will be treated as invalid in other components, e.g. SlotPool and SlotManager. We have to remove a lot of sanity checks with this change, which is error-prone. The evidence is that there are still some sanity checks that have not been removed, e.g. sanity checks in AllocatedSlotInfo. We propose to assign an increasing number larger than the numberOfSlot to dynamic slots. In this way, we can decouple the JM and RM with the dynamic slot logic. -- This message was sent by Atlassian Jira (v8.3.4#803005)
