[jira] [Created] (FLINK-9909) Remove cancellation of input futures from ConjunctFutures

Till Rohrmann created FLINK-9909:
------------------------------------

             Summary: Remove cancellation of input futures from ConjunctFutures
                 Key: FLINK-9909
                 URL: https://issues.apache.org/jira/browse/FLINK-9909
             Project: Flink
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.5.1, 1.6.0, 1.7.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.5.2, 1.6.0


With FLINK-8749, we introduced that a {{ConjunctFutures}} cancels all of its input futures if it is cancelled. This has, however, some unpleasant side effects since a all of the cancelled future's completing callbacks won't be called. Since this can lead to subtle bugs like in FLINK-9908, I would propose to remove this feature and require the user to do the cancellation of input futures explicitly.
