我正在使用 HBase 和 Hadoop，并让它们在我的机器上以伪分布式模式运行。我有写入 HBase 的表，这些表存储在 hdfs 上的“hbase”目录中，如下所示

$HADOOP_HOME/bin/hadoop fs -ls /Found 3 items
drwxr-xr-x   - robocode supergroup          0 2013-04-17 11:48 /Users
drwxr-xr-x   - robocode supergroup          0 2013-04-17 11:26 /hbase
drwxr-xr-x   - robocode supergroup          0 2013-04-08 15:07 /usr

我想将此 hbase 目录从 hdfs 备份到我桌面上的目录，以便以后可以将其还原到 hbase/hdfs。我正在使用如下 distcp，它似乎运行良好，但是当它完成时，我的桌面上没有 hbase 目录的迹象

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

关于我要去哪里错的任何想法？
