Apache spark Spark 1.5.1独立群集-线程“main”akka.actor.ActorNotFound中出现异常：找不到的actor

通过spark submit或java代码将作业提交到集群时，我遇到了一些问题。作业不断失败，stderr记录在SPARK_HOME/work/app_id下。。始终显示相同的错误：

你知道是什么原因吗？运行netstat表明没有进程侦听端口53411。

我猜错误消息是：

与远程系统的关联 [阿卡。tcp://sparkDriver@主节点：53411]已失败

告诉你主工沟通有问题

我以前犯过这个错误，我的建议是：

确保您的主地址正确，检查 检查防火墙，确保端口未被阻止。Spark将使用一些随机端口号进行通信 确保你的内存足够大，如果没有足够的资源，有时也会产生类似的错误 您可以在端口4040和18080监视集群状态，也许这也会给您一些有用的线索
