我试图复制文件从hdfs到s3使用 distcp 通过执行以下命令
hadoop distcp -fs.s3a.access.key=AccessKey -fs.s3a.secret.key=SecrerKey \
s3n://testbdr/test2 hdfs://hostname:portnumber/tmp/test但我得到以下错误：
17/09/05 02:59:30 ERROR tools.DistCp: Invalid arguments:

要传递配置参数，必须使用
-D```hadoop distcp -Dfs.s3a.access.key=AccessKey -Dfs.s3a.secret.key=SecrerKey
s3n://testbdr/test2 hdfs://hostname:portnumber/tmp/test

旧命令
hadoop distcp-dfs.s3a.access.key=accesskey-dfs.s3a.secret.key=secretkey\s3n://testbdr/test2hdfs://hostname：端口号/tmp/测试
修正指令
hadoop distcp-dfs.s3n.awsaccesskeyid=accesskey-dfs.s3n.awssecretaccesskey=secretkey\s3n://testbdr/test2hdfs://hostname：端口号/tmp/测试
