> Test Relocatable Savepoints
> ---------------------------
>
> Key: FLINK-18091
> URL: https://issues.apache.org/jira/browse/FLINK-18091
> Project: Flink
> Issue Type: Sub-task
> Components: Tests
> Reporter: Stephan Ewen
> Assignee: Congxian Qiu(klion26)
> Priority: Major
> Labels: release-testing
> Fix For: 1.11.0
>
>
> The test should do the following:
> * take a savepoint. needs to make sure the job has enough state that there
> is more than just the "_metadata" file
> * copy it to another directory
> * start the job from that savepoint by addressing the metadata file and by
> addressing the savepoint directory
> We should also test that an incremental checkpoint that gets moved fails with
> a reasonable exception.
