我试图使用所有Amazon EC2 m4.large实例启动并运行Apache Spark Cluster。 我的设置目前如下：在Apache Spark独立模式下提交python示例应用程序时出错
- 驾驶员EC2实例
- 火花法师
- 两个星火奴隶
我已经安装了星火2.0.2上的驱动程序，并开发了使用我下载并安装的spark-ec2脚本的集群https://github.com/amplab/spark-ec2/tree/branch-2.0
我可以在眉毛上看到我的Spark Master的Web UI呃，以及它上面的两个从节点。
所以，现在当我尝试使用以下命令我$ SPARK_HOME提交一个示例应用程序实例/ src目录/主/蟒蛇/ pi.py的建议here：
./bin/spark-submit --master spark://ip-172-31-43-158.ec2.internal:7077 examples/src/main/python/pi.py 1000
我得到以下错误：
[[email protected] spark]$ ./bin/spark-submit --master spark://ip-172-31-43-158.ec2.internal:7077 examples/src/main/python/pi.py 1000

This是我的Spark Master Web UI的屏幕截图。
任何指针，我哪里出错了？ 我真的很感激这方面的一些帮助！
