Release Note:

Hide
When restoring from a savepoint or retained externalized checkpoint you can choose the mode in which you want to perform the operation. You can choose from CLAIM, NO_CLAIM, LEGACY(the old behaviour).

In CLAIM mode Flink takes ownership of the snapshot and will potentially try to remove the snapshot at a certain point in time. On the other hand the NO_CLAIM mode will make sure Flink does not depend on the existence of any files belonging to the initial snapshot.

For a more thorough description see the documentaion.
