             Summary: The DirectRunner can complete before reporting the 
results of all ModelEnforcements
                 Key: BEAM-819
                 URL: https://issues.apache.org/jira/browse/BEAM-819
             Project: Beam
          Issue Type: Bug
          Components: runner-direct
            Reporter: Thomas Groh
            Assignee: Thomas Groh


The termination condition in the 
ExecutorServiceParallelExecutor.MonitorRunnable checks to see if the evaluation 
context is done, among other things. Due to the signatures of ModelEnforcement, 
output is committed before ModelEnforcement runs to ensure that the enforcement 
has access to the final elements. If the transform that performs 
ModelEnforcement completes, and all PTransforms are done, the pipeline can 
shutdown before model enforcement fails.
