What kind of state backend where you using for the checkpoints? If there is a bug that prevents us from deleting the savepoint files automatically, we can do a manual workaround and delete the checkpoints files manually. With Flink 1.3 this becomes very straight forward as savepoint data all go to a self contained directory that can be deleted manually.
