-------------------------------------

             Summary: Fail globally when not resuming from the latest checkpoint in regional failover
                 Key: FLINK-20465
                 URL: https://issues.apache.org/jira/browse/FLINK-20465
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.12.0
            Reporter: Till Rohrmann
             Fix For: 1.13.0


As a follow up for FLINK-20290 we should assert that we resume from the latest checkpoint when doing a regional failover in the {{SourceCoordinators}} in order to avoid losing input splits (see FLINK-20427). If the assumption does not hold, then we should fail the job globally so that we reset the master state to a consistent view of the state. Such a behaviour can act as a safety net in case that Flink ever tries to recover from not the latest available checkpoint.
