Subject [jira] [Created] (FLINK-2063) Streaming checkpoints consider only input and output vertices

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

             Summary: Streaming checkpoints consider only input and output vertices
                 Key: FLINK-2063
                 URL: https://issues.apache.org/jira/browse/FLINK-2063
             Project: Flink
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 0.9
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 0.9


Currently, the streaming checkpoint coordinator is configured only with the list of input
and output vertices as stateful vertices.

Checkpoint confirmations from intermediate vertices are ignored.

Since the runtime assumes that all vertices participate in checkpointing anyways (all of them
send acknowledge messages), the coordinator should be configured accordingly.
