[jira] [Created] (BEAM-1594) JOB_STATE_DRAINED should be terminal for waitUntilFinish()

             Summary: JOB_STATE_DRAINED should be terminal for waitUntilFinish()
                 Key: BEAM-1594
                 URL: https://issues.apache.org/jira/browse/BEAM-1594
             Project: Beam
          Issue Type: Bug
          Components: runner-dataflow
            Reporter: Eugene Kirpichov
            Assignee: Eugene Kirpichov


Dataflow runner supports pipeline draining for streaming pipelines, which stops consuming input and waits for all watermarks to progress to infinity and then declares the pipeline complete. When watermarks progress to infinity after a drain request, the Dataflow runner will mark the job DRAINED (In the future, when watermarks progress to infinity without a drain request, it will mark the job DONE instead). JOB_STATE_DRAINED is logically a terminal state - no more data will be processed and the pipeline's resources are torn down - and waitUntilFinish() should terminate if the job enters this state.
