------------------------------------

             Summary: Last remembered metadata window per dstream is not 
cleared upon context graceful stop
                 Key: SPARK-16160
                 URL: https://issues.apache.org/jira/browse/SPARK-16160
             Project: Spark
          Issue Type: Bug
          Components: Streaming
            Reporter: Ahmed Mahran
            Priority: Minor


When stopping a streaming context gracefully, the last remembered window for 
each dstream is not cleared. If the streaming context is stopped without 
stopping the spark context, the persisted garbage rdds would still be there 
especially when there is a relatively large remember duration in case of 
windowing or checkpointing.
