我正在尝试通过执行以下命令,使用distcp
将文件从HDFS复制到S3
hadoop distcp -fs.s3a.access.key=AccessKey -fs.s3a.secret.key=SecrerKey \
s3n://testbdr/test2 hdfs://hostname:portnumber/tmp/test
但是我收到以下错误:
17/09/05 02:59:30 ERROR tools.DistCp: Invalid arguments:
java.lang.IllegalArgumentException: Both source file listing and source paths present

Invalid arguments: Both source file listing and source paths present
usage: distcp OPTIONS [source_path...] <target_path>
OPTIONS
-append Reuse existing data in target files and
append new data to them if possible
-async Should distcp execution be blocking
最佳答案
要传递配置参数,您必须使用-D
hadoop distcp -Dfs.s3a.access.key=AccessKey -Dfs.s3a.secret.key=SecrerKey \
s3n://testbdr/test2 hdfs://hostname:portnumber/tmp/test
关于hadoop - java.lang.IllegalArgumentException:源文件列表和源路径都存在,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/46051271/
