Hadoop -mkdir : - Could not create the Java Virtual Machine

I have configured the Hadoop 1.0.4 and started the following without any issue:

1. $ start-dfs.sh : -Works fine

2. $ start-mapred.sh : - Work fine

3. $ jps  (Output is below)

Out put: 

rahul@rahul-Inspiron-N4010:/usr/local/hadoop-1.0.4/bin$ jps

6964 DataNode

7147 SecondaryNameNode

6808 NameNode

7836 Jps

7254 JobTracker

7418 TaskTracker

But facing issue: While issuing command 

rahul@rahul-Inspiron-N4010:/usr/local/hadoop-1.0.4/bin$ hadoop -mkdir /user

Getting following error

Unrecognized option: -mkdir
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I applied the patch : HDFS-1943.patch but not use full

Should be: hdfs dfs -mkdir /user

Consult documentation at http://hadoop.apache.org/docs/r1.0.4/file_system_shell.html
