[jira] [Created] (SPARK-18280) Potential deadlock in `StandaloneSchedulerBackend.dead`

Shixiong Zhu created SPARK-18280:
------------------------------------

             Summary: Potential deadlock in `StandaloneSchedulerBackend.dead`
                 Key: SPARK-18280
                 URL: https://issues.apache.org/jira/browse/SPARK-18280
             Project: Spark
          Issue Type: Bug
            Reporter: Shixiong Zhu


"StandaloneSchedulerBackend.dead" is called in a RPC thread, so it should not call "SparkContext.stop" in the same thread. "SparkContext.stop" will block until all RPC threads exit, if it's called inside a RPC thread, it will be dead-lock.
