Ubuntu 在客户机模式下启动pyspark时，执行器丢失

我能够在一台笔记本电脑上以“纱线客户端”模式运行pyspark，我正在尝试在另一台笔记本电脑上进行设置。然而，这次我无法让它运行

当我尝试在Thread客户机模式下启动pyspark时，会出现以下错误。我使用动态资源分配，已将SPARK_EXECUTOR_内存设置为小于容器内存。我正在使用hadoop 2.6.4、spark 1.6.1、ubuntu 15.10

错误是否可能是由于网络问题造成的

这不是（）种吗？@RamPrasadG谢谢你的链接。我现在可以运行spark了，奇怪的是我什么都没做。我重新启动了ubuntu好几次，结果都没用。我放弃了，睡了，醒了，打开笔记本电脑，试了试，这次成功了！我的最后一个变化是在hadoop中从jdk 8切换到jdk 7。也许spark不支持jdk 8No。。Spark支持JDK8，我认为这是您的洗牌服务问题。内蒂还是尼奥。。许多帖子都在讨论洗牌服务。当他们把它换成其他的时候，他们就通过了
