CoarseGrainedScheduler
## What changes were proposed in this pull request?
When driver stopping, there is a error:
17/12/12 18:30:16 INFO MapOutputTrackerMasterEndpoint:
MapOutputTrackerMasterEndpoint stopped!
17/12/12 18:30:16 ERROR TransportRequestHandler: Error while invoking
RpcHandler#receive() for one-way message.
org.apache.spark.SparkException: Could not find CoarseGrainedScheduler.

Because the endpoint of CoarseGrainedScheduler is stopped, this error is
not problem, so i think this error should not be printed.
