You don't call this via hadoop.
You can either run:

hdfs dfs -ls /

Or:

hadoop fs -ls /

I am not sure it's going to answer your question but

  Hadoop version 1

All command line utilities were in 'hadoop install dir'/bin directory. All hadoop commands are invoked by the bin/hadoop script

  Hadoop version 2
  Commands live in two directories.

bin : Most used commands like hadoop, mapred ..etc
sbin: Administrative commands like start-all.sh (command used to start all Hadoop daemons ..etc) and stop-all.sh
