在使用 Spark 完成我的第一步时，我遇到了从应用程序代码提交作业到集群的问题。挖掘日志，我注意到主日志上有一些周期性的 WARN 消息：
15/10/08 13:00:00 WARN remote.ReliableDeliverySupervisor: Association with remote system [akka.tcp://sparkDriver@192.168.254.167:64014] has failed, address is now gated for [5000] ms. Reason: [Disassociated]
问题是我们的网络上不存在 IP 地址，也没有在任何地方配置。当它尝试执行任务时，工作日志上会显示相同的错误 ip（错误的 ip 传递给 --driver-url）：

知道我做错了什么，如何解决？
Java 版本是 1.8.0_20，我使用的是预构建的 Spark 二进制文件。
谢谢！
