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

             Summary: Graceful shutdown for Spark Streaming does not work in Standalone cluster
mode
                 Key: SPARK-4986
                 URL: https://issues.apache.org/jira/browse/SPARK-4986
             Project: Spark
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.2.0
            Reporter: Jesper Lundgren


When using the graceful stop API of Spark Streaming in Spark Standalone cluster the stop signal
never reaches the receivers. I have tested this with Spark 1.2 and Kafka receivers. 

ReceiverTracker will send StopReceiver message to ReceiverSupervisorImpl.
In local mode ReceiverSupervisorImpl receives this message but in Standalone cluster mode
the message seems to be lost.

Sent my own string message as a stop signal from ReceiverTracker to ReceiverSupervisorImpl
and it works as a workaround.
