             Summary: Have PipelineExecution implement ListenableFuture
                 Key: CRUNCH-273
                 URL: https://issues.apache.org/jira/browse/CRUNCH-273
             Project: Crunch
          Issue Type: Improvement
          Components: Core
            Reporter: Josh Wills
            Assignee: Josh Wills


When running pipelines from the client asynchronously, it would be nice to be 
able to add some callbacks that would execute when the pipeline of jobs 
finishes. It seems to me that the best way to do that is to have the 
PipelineExecution interface extend ListenableFuture<PipelineResult>, which 
supports adding (Runnable, Executor) methods that are executed at the end of a 
pipeline run.
