6. 检查步骤5运行结果
[linuxidc@hadoop02 hadoop-1.1.2]$ ./bin/hadoop fs -ls out
Found 3 items
-rw-r--r-- 1 linuxidc supergroup 0 2013-09-10 14:20 /user/linuxidc/out/_SUCCESS

7. 删除HDFS测试文件和目录
[linuxidc@hadoop02 hadoop-1.1.2]$ ./bin/hadoop fs -rmr TEST out
Deleted hdfs://hadoop01:9000/user/linuxidc/TEST
Deleted hdfs://hadoop01:9000/user/linuxidc/out
[linuxidc@hadoop02 hadoop-1.1.2]$
至此，测试结束。
