I want to remove hadoop directory,so I use hadoop fs -rmr,but it can't remove,why?

[hdfs@localhost hadoop-2.2.0]$ hadoop fs -ls

drwxr-xr-x   - hdfs supergroup          0 2014-07-01 17:52 QuasiMonteCarlo_1404262305436_855154103

And I try mkdir a directory,but I still fail
[hdfs@localhost hadoop-2.2.0]$ hadoop fs -mkdir abc
mkdir: Cannot create directory /user/hdfs/abc. Name node is in safe mode.

How can I do it?  Thanks.
