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

             Summary: LibraryCacheManager should track execution IDs of library registrations
                 Key: FLINK-1205
                 URL: https://issues.apache.org/jira/browse/FLINK-1205
             Project: Flink
          Issue Type: Bug
          Components: Distributed Runtime
    Affects Versions: 0.8-incubating
            Reporter: Stephan Ewen
             Fix For: 0.8-incubating


Currently, it is hard to guarantee that on a failed execution attempt, the libraries are de-registered exactly once. Only references per JobId are tracked. If we track the registered ExecutionAttempts, we can make sure we de-register only if we have not yet de-registered that execution attempt.
