[jira] [Created] (FLINK-23021) Check if the restarted job topology
is consistent on restart
Yun Gao created FLINK-23021:
-------------------------------
Summary: Check if the restarted job topology is consistent on restart
Key: FLINK-23021
URL: https://issues.apache.org/jira/browse/FLINK-23021
Project: Flink
Issue Type: Sub-task
Reporter: Yun Gao
Users might modify the job topology before restart for external checkpoint and savepoint. To overcome this issue, we would need to check if a fully finished operator have been added after a non-fully-finished operator. If so, we would throw exception to disallow this situation or re-mark the fully finished operator as alive.
