Question

我试图创建一个＆＃34; Step＆＃34;并将许多小文件合并为一个，所以我可以将它分开几天。问题在于，我是在尝试运行而不是让我。

执行它对我来说效果很好：

hadoop distcp s3n://buket-name/output-files-hive/* s3n://buket-name/files-hive/test

但是如果我已经输入命令＆＃34; group by＆＃34;或者＆＃34; srcPattern＆＃34;它没有给我任何东西。

创建＆＃34;步骤＆＃34;在Amazon EMR控制台中，给我所有时间错误。你指出了文件

命令：

aws emr add-steps --cluster-id j-XXXXXXX --steps Name="S3DistCp step",Jar="command-runner.jar",Args=["spark-submit","--src=s3n://buket-name/output-files-hive/output-files-hive/*","--dest=s3n://buket-name/output-files-hive/files-hive/test/"]

错误：

Answer 1

在emr amazon的新版本中，不再是necesartio包含.jar文件，定义S3DistCp参数。

aws emr add-steps --cluster-id j-XXXXXX --steps Name="S3DistCp step V3",Jar="command-runner.jar",Args=["s3-dist-cp","--src=s3n://buket-name/output-files-hive/","--dest=s3n://buket-name/files-hive/test/"]

使用exitCode，Amazon Emr Hadoop，S3DistCp失败了
