Maybe because you have not started hadoop service.

Open terminal and run:

$ sudo jps
$ sudo service hadoop-master restart
$ sudo jps

After this check whether these 4 daemons are up and running or not: Namenode,datanode,Resource manager, Node manager. If yes then try the command hdfs dfs -ls / again.
