从emr集群主机外部使用spark submit

我们在aws elastic mapreduce(emr)和spark 1.6.1中运行了一个hadoop集群。进入集群主服务器并提交spark作业没有问题,但是我们希望能够从另一个独立的ec2示例提交它们。
另一个“外部”ec2示例设置了安全组,以允许进出emr示例主示例和从示例的所有tcp通信。它有一个直接从apache站点下载的spark二进制安装。
在将/etc/hadoop/conf文件夹从master复制到这个示例并相应地设置$hadoop\u conf\u dir之后,在尝试提交sparkpi示例时,我遇到了以下权限问题:

如果使用集群部署模式提交,则没有区别。有问题的用户是'external'ec2示例上的本地用户(我们有多个开发人员帐户),该示例在集群的主服务器或从服务器上都不存在(甚至在本地,用户的主目录在/home中,而不是/user中)。
我不知道发生了什么事。非常感谢您的帮助。

从主机以外的机器运行spark submit需要几件事:
需要在hdfs中创建与提交的用户匹配的用户
例如,使用hue控制台,或者直接创建/user/name文件夹并使用 hadoop fs 主程序上的命令行工具
外部机器和集群主设备和从设备之间的所有必要端口必须在两个方向上打开(或者,所有tpc通信)。
如果在aws ec2 emr环境中,机器的安全组、主机和从机可以显式地允许来自其他组。
可能还需要在主服务器上创建用户作为linux帐户。
