Question

我正在尝试使用以下内容使用Amazon ec2进行提交：

spark-submit --packages org.apache.hadoop:hadoop-aws:2.7.1 --master spark://amazonaws.com SimpleApp.py

我最终得到以下错误。似乎它正在寻找hadoop。我的ec2集群是使用spark-ec2命令创建的。

Answer 1

您正在使用--packages org.apache.hadoop:hadoop-aws:2.7.1选项提交作业，并且作业正尝试通过从公共maven repo下载包来解决依赖关系。但是，此错误表示无法访问maven回购。

Server access error at url https://repo1.maven.org/maven2/org/apache/hadoop/hadoop-aws/2.7.1/hadoop-aws-2.7.1.pom (java.net.NoRouteToHostException: No route to host (Host unreachable))

您可能想要检查火花主人是否可以访问互联网。
