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

             Summary: Make the queue capacity of LiveListenerBus configurable.
                 Key: SPARK-18550
                 URL: https://issues.apache.org/jira/browse/SPARK-18550
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: Zhan Zhang
            Priority: Minor


We meet issues that driver listener bus cannot catch up the speed of incoming event. Current value is fixed as 1000. This value should be configurable per job. Otherwise, when event is dropped, the UI is totally useless.

Bus: Dropping SparkListenerEvent because no remaining room in event queue.
