> Savepoints do not work with ExternallyInducedSources
> ----------------------------------------------------
>
> Key: FLINK-25256
> URL: https://issues.apache.org/jira/browse/FLINK-25256
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.14.0, 1.13.3, 1.12.7
> Reporter: Dawid Wysakowicz
> Assignee: Arvid Heise
> Priority: Major
> Labels: pull-request-available, stale-assigned
> Fix For: 1.16.0, 1.14.6
>
>
> It is not possible to take a proper savepoint with
> {{ExternallyInducedSource}} or {{ExternallyInducedSourceReader}} (both legacy
> and FLIP-27 versions). The problem is that we're hardcoding
> {{CheckpointOptions}} in the {{triggerHook}}.
> The outcome of current state is that operators would try to take checkpoints
> in the checkpoint location whereas the {{CheckpointCoordinator}} will write
> metadata for those states in the savepoint location.
> Moreover the situation gets even weirder (I have not checked it entirely), if
> we have a mixture of {{ExternallyInducedSource(s)}} and regular sources. In
> such a case the location and format at which the state of a particular task
> is persisted depends on the order of barriers arrival. If a barrier from a
> regular source arrives last the task takes a savepoint, on the other hand if
> last barrier is from an externally induced source it will take a checkpoint.
