> 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
> Priority: Critical
> Fix For: 1.13.0, 1.12.1
>
>
> 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.
