scala – Spark驱动程序与主服务器解除关联并删除

spark-submit --master spark://spark-master:7077 --class tests.elements target/scala-2.10/zzz-project_2.10-1.0.jar

经过一段时间运行得很好,它终止了终端上的最后几行

分别. hdfs或spark似乎没有其他错误.

我怀疑错误在于主日志,第三行(15/08/19 16:15:44 INFO master.Master：akka.tcp：//sparkDriver@192.168.1.64：46823已取消关联,删除它. )但我无法弄清楚为什么.我尝试将spark.akka.heartbeat.interval更改为100,如某些帖子所示,但没有运气.任何人都知道它为什么会发生以及如何解决这个问题？非常感谢.
