Are you just trying to get this running for the first time?
To format a new distributed filesystem you can use:
$ bin/hadoop namenode -format
As it says in the docs:
*You need to do this the first time you set up a Hadoop installation.
Do notformat a running Hadoop filesystem, this will cause all your
data to be
erased. Before formatting, ensure that the dfs.name.dir directory exists. If
you just used the default, then mkdir -p /tmp/hadoop-username/dfs/name will
create the directory. To format the filesystem (which simply initializes the
directory specified by the dfs.name.dir variable).** *

I did that but it didn't work ( I got the same message )
my updated /etc/hosts file is
127.0.0.1 localhost mem
192.168.5.236 localhost mem
I've also tried this :
192.168.5.236 localhost mem
127.0.0.1 localhost mem
which gave the message
Retrying connect to server: localhost/192.168.5.236:50000

I've set up a standalone hadoop server , and when I run

I get the following message ( repeating 10 times ) :

Any happen would be appreciated.
