Ubuntu13.04 problem

Originally good, just configured Hadoop pseudo distributed environment, ready to run under wordcount, but the input
hadoop fs -ls
When prompted,
hadoop: command not found

I find a lot of information on the Internet, as with the HADOOP_HOME, but I don't know where the configuration is correct, then plan to restart to restart the Hadoop service

The issue came, after rebooting the system has been stuck in the landing interface, I enter the correct password, black out and then back to the login interface, if you enter the wrong password password mistake, now simply can not login into Ubuntu, people have encountered such a situation? ? ?
Or hadoop:command not found suggest the above error line. . . .

To thank!!

This version is very unstable, estimate is the lack of any problems.
Suggestions put back 12.04
