[jira] [Created] (SPARK-16487) Some batches might not get marked as fully processed in JobGenerator

Ahmed Mahran created SPARK-16487:
------------------------------------

             Summary: Some batches might not get marked as fully processed in JobGenerator
                 Key: SPARK-16487
                 URL: https://issues.apache.org/jira/browse/SPARK-16487
             Project: Spark
          Issue Type: Bug
          Components: Streaming
            Reporter: Ahmed Mahran
            Priority: Trivial


In JobGenerator, the code reads like that some batches might not get marked as fully processed. In the following flowchart, the batch should get marked fully processed before endpoint C however it is not. Currently, this does not actually cause an issue, as the condition {code}(time - zeroTime) is multiple of checkpoint duration?{code} always evaluates to true as the checkpoint duration is always set to be equal to the batch duration.
