Is there any line in your host file like
127.0.1.1 localhost ???? if so coment it with #
did you format your namenode??? if not format it.
192.168.2.118 yourhostname
^ ^

This will be ip this is a name
of your machine
what is your hostname (you can get it using command "hostname" on terminal )
follow these and format your name node and try to start.
and also try to change the port no you are using give it something like
9000 or some other which is not already used
which you can veryfy by giving command "netstat -nl | grep 'Ip you want to
use'" if this gives some output means that port is acquired and try some
other port..
Let me know if it solved your problem...
