It could be a resource problem. Try to increase the number of cores and executor and also to assign more RAM to the application then you should increase the partition number of your RDD by calling a repartition. The ideal number of partitions depends on previous settings. Hope this helps.
说明:程序中用到repartition前后不一致导致这个问题
问题:
ERROR scheduler.LiveListenerBus: SparkListenerBus has already stopped! Dropping event SparkListenerExecutorMetricsUpdate(1,WrappedArray())
因为spark没有关闭导致
Spark: Could not find CoarseGrainedScheduler
