[jira] [Created] (FLINK-20305) Iterative job with maxWaitTimeMillis does not terminate

Till Rohrmann created FLINK-20305:
-------------------------------------

             Summary: Iterative job with maxWaitTimeMillis does not terminate
                 Key: FLINK-20305
                 URL: https://issues.apache.org/jira/browse/FLINK-20305
             Project: Flink
          Issue Type: Bug
          Components: API / DataStream
            Reporter: Till Rohrmann


While testing the {{DataStream}} API, I noticed that an iterative job with {{maxWaitTimeMillis}} set, sometimes did not terminate depending on the used parallelism. Since I used a bounded source with few events, it looked a bit as if the iteration tasks couldn't terminate if they didn't receive an event. The corresponding testing job including test data can be found [here|https://github.com/tillrohrmann/flink-streaming-batch-execution/tree/iteration-problem].
