------------------------------------

             Summary: Naive version of atomic stop signal with savepoint
                 Key: FLINK-4717
                 URL: https://issues.apache.org/jira/browse/FLINK-4717
             Project: Flink
          Issue Type: New Feature
          Components: State Backends, Checkpointing
    Affects Versions: 1.2.0
            Reporter: Till Rohrmann
            Priority: Minor
             Fix For: 1.2.0


As a first step towards atomic stopping with savepoints we should implement a cancel command which prior to cancelling takes a savepoint. Additionally, it should turn off the periodic checkpointing so that there won't be checkpoints executed between the savepoint and the cancel command.
