Re: Hadoop Pseudo-configuration
Helllo Shagun,

        Make sure you have set the required config parameters correctly.
Also, modify the line containing "" to "" in your
"etc/hosts" file and add the hostname of your VM along with the IP in the
etc/hosts file if you are using FQDN.

If you still face any issue, have a look at this
