emr step命令运行程序配置单元脚本

我正在尝试运行一个配置单元脚本,它位于emr集群上的s3上。
当通过ssh连接到emr集群时,输入

"hive -f s3://..."

作品。但是,我希望这是自动完成的,所以我创建了一个python脚本,并尝试向集群添加一个步骤。但是,我无法运行此步骤,即使是通过aws控制台手动添加此步骤。对于jar文件,我指定了“command runner.jar”,但是不管我使用什么参数(我用另一个线程建议的“hive-fs3://…”尝试了它,但没有成功),这个步骤总是立即失败。当切换到script-runner.jar而不是command runner时,我可以以某种方式让它与命令一起工作

/usr/share/aws/emr/scripts/hive-script --run-hive-script --args -f s3://...

然而,几秒钟后我得到了一个错误,在stderr中我会发现这个错误。

理想情况下,我希望通过使用command-runner.jar来解决这个问题。有人能告诉我应该使用的正确参数吗(在aws控制台和/或add\u job\u flow的boto3参数中)?

好吧,对于任何有同样问题的人来说:原来我错过了在emr集群的应用程序中添加“hive”。。。

从s3运行配置单元脚本

hadoop jar /var/lib/aws/emr/step-runner/hadoop-jars/command-runner.jar hive-script --run-hive-script --args -f  s3://path/scripts/hive_show_table.hql
