> broadcast variables can cause lots of warning messages on shutdown
> ------------------------------------------------------------------
>
> Key: SPARK-14405
> URL: https://issues.apache.org/jira/browse/SPARK-14405
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Reporter: Thomas Graves
> Priority: Major
> Labels: bulk-closed
>
> when using broadcast variables and lots of executors you get a lot of warning messages on shutdown.
> Messages from LiveListenerBus are like:
> SparkListenerBus has already stopped! Dropping event .....
> The issue here is the order of the stop. In SparkContext.stop, ListenerBus.stop is earlier than SparkEnv.stop is called and thus it gets shutdown before the broadcast manager or with https://github.com/apache/spark/pull/12113 the MapOutputTracker.
