Bug Fix: In yarn-cluster mode, ApplicationMaster does not clean up corre...
...ctly at the end of the job if users call sc.stop manually. There are two
minor bugs:
1. At the end of a job, "ApplicationMaster" will ask for resources and
launch containers repeatedly. These newly launched containers keep trying to
contact with the already-stopped driver and fianally fail. When the container
failure number reaches the max value, this job's FinalStatus wil be marked as
FAILED.
2. After the driver asks to stop executors, "BlockManager" of executors
will try to contact the already-stoppped "BlockManagerMasterActor" of the
driver. Unfortunately, all the connecting attempts will fail, and then the
executor process will crash with a non-zero Exit Code.
