大家好:我正在尝试通过 s3 在 EMR 集群中获取 s3 distcp jar 文件:

s3cmd get s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar

但是,“get”命令不起作用:

ERROR: Skipping libs/s3distcp/: No such file or directory

该文件也存在于其他 s3 区域中,所以我什至尝试过:

s3cmd get s3://us-east-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar

但是ecommand仍然失败。但是,唉——这个 .jar 文件显然存在,当我们运行“s3cmd ls”时,我们可以看到它被列出来。有关详细信息,请参见下文(以 eu-west 地区为例):

hadoop@ip-10-58-254-82:/mnt$ s3cmd ls s3://eu-west-1.elasticmapreduce/libs/s3distcp/
Bucket 'eu-west-1.elasticmapreduce':

2012-06-27 21:27   1893846   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.latest/s3distcp.jar

以上似乎证实了,事实上该文件是存在的。

*我怎样才能使“get”命令适用于这个文件?*

jar 工作正常,您可以粘贴 get 命令后收到的错误消息吗?

:s3cmd ls s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar

2012-06-01 00:32   3614287   s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar

:s3cmd get s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar

s3://eu-west-1.elasticmapreduce/libs/s3distcp/1.0.1/s3distcp.jar -> ./s3distcp.jar  [1 of 1]
