Question

我正在运行Spark Standalone群集，在提交应用程序时，火花驱动程序因以下错误而停止。

16/01/12 23:26:14 INFO Worker: Asked to kill executor app-20160112232613-0012/0

我是Spark及其处理的新手。请帮助我。

Answer 1

错误不是由java.io.IOException引起的，因为您可以清楚地看到16/01/12 23:26:14 INFO Worker: Asked to kill executor app-20160112232613-0012/0。之后当spark尝试写入日志文件时会引发此异常，您还将在其中查看错误原因。

即使您使用root权限spark-submit运行，也是spark用户编写文件。我猜你这台笔记本电脑上正在运行。尝试在spark文件夹上运行sudo chmod -R 777。

Answer 2

在我的情况下，问题是，spark驱动程序无法从提交的可执行jar中获取依赖项。合并所有依赖项并将它们转换为单个可执行文件。它解决了这个问题。

请遵守我的术语:)
