我正在尝试将目录从hdfs备份到本地目录。我有一个hadoop/hbase集群在ec2上运行。我设法做了我想在我的本地机器上以伪分布式运行的事情，但是现在我完全分布式了，同样的步骤也失败了。以下是对伪分布式系统有效的方法

hadoop distcp hdfs://localhost:8020/hbase file:///Users/robocode/Desktop/

下面是我在ec2上尝试的hadoop namenode（hbase master）

ec2-user@ip-10-35-53-16:~$ hadoop distcp hdfs://10.35.53.16:8020/hbase file:///~/hbase

我得到的错误如下

13/04/19 09:07:40 INFO tools.DistCp: srcPaths=[hdfs://10.35.53.16:8020/hbase]
13/04/19 09:07:40 INFO tools.DistCp: destPath=file:/~/hbase
