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

             Summary: Stopping Streaming Context (sometimes) crashes master
                 Key: SPARK-7600
                 URL: https://issues.apache.org/jira/browse/SPARK-7600
             Project: Spark
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.3.1
            Reporter: Marius Soutier


In my streaming job (that uses actorStreams) I'm stopping the SparkStreaming context via ssc.stop(stopSparkContext = true, stopGracefully = true). Sometimes this leads to the Spark master being in a permanent error state that just displays an error page instead of the UI.

The following is being logged when trying to access the master UI:
