I have installed Hadoop and HDFS using this tutorial
http://codesfusion.blogspot.com/2013/10/setup-hadoop-2x-220-on-ubuntu.html
Everything is fine.
I am also able to create directories and use them using
hadoop fs -mkdir /tmp
hadoop fs -mkdir /small
I can also say
hadoop fs -ls /
However I am following a tutorial in which the trainer does
hadoop fs -mkdir temp
hadoop fs -ls
now on my machine when I issue the above command it says
ls: `.': No such file or directory
In my training video the command hadoop fs -ls works perfectly. Why should I specify the "/"?
Also I am getting this warning in all my commands
13/12/28 20:23:52 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
But in my trainers video there is no such warning.
My configuration file is exactly as the tutorial above and I can also see all management UIs at
http://aarav-pc:8042/
http://aarav-pc:50070/
http://aarav-pc:8088/
So my question is what is wrong with my configuration and why is my system behaving differently than the training video?
