Command "hadoop fs -ls ." does not work

Question

I think I have installed hadoop correctly. If I do jps I can see the namenode and datanode, no problem.

When I type hadoop fs -ls . I get the error:

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /opt/db/hadoop-2.4.1/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
14/08/08 12:42:44 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
ls: '.': No such file or directory

When I type hadoop dfs -ls . I get the error:

DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /opt/db/hadoop-2.4.1/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.

14/08/08 12:43:27 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
ls: '.': No such file or directory

And when I type hadoop hdfs -ls . I get the error:

Error: Could not find or load main class hdfs

This is regardless of whether I put '.' or '/' or whatever directory I'm in.

What does this all mean? How can I get normal, expected output? What am I missing?

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib" Add these two lines in .bashrc and reopen your terminal and try restarting hadoop. — Y.Prithvi, Aug 08 '14 at 10:49
oh... no I'll do that. I realised it took away the warning anyway which is great! I'll restart now — Ree, Aug 08 '14 at 10:56
ok if I try 'hadoop dfs -ls /' i get the following: `DEPRECATED: Use of this script to execute hdfs command is deprecated. Instead use the hdfs command for it. 14/08/08 12:59:47 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable ` — Ree, Aug 08 '14 at 11:00
So then I tried: hadoop hdfs -ls / and got `Error: Could not find or load main class hdfs` — Ree, Aug 08 '14 at 11:01
are there any files in HDFS? why don't check in UI http:/localhost/50070 — Y.Prithvi, Aug 08 '14 at 11:11
