What does your /etc/hosts file contain? Maybe add localhost and node24.nise.local as a name at the 127.0.0.1 line.

Then add `node24.nise.local` to this line. – Dunaril Sep 21 '11 at 08:31

Yes. It works once you add domain name in local host entry /etc/hosts

127.0.0.1  testdomain  localhost.localdomain localhost

Add following line in the /etc/hosts file

  127.0.0.1  localhost.localdomain localhost node24.nise.local

Replace node24.nise.local with your host name.

Go to terminal and just run:

$ hostname localhost

(or whatever is your host name)

In AWS EC2, when you install Cassandra you can have this problem because of the initially configured hostname which is set to ip-x-x-x-x being x-x-x-x the EC2 instance private address. The steps to solve it:

Edit network configuration file /etc/sysconfig/network

HOSTNAME=[myservername]
Edit hosts file:

sudo vi /etc/hosts
Add hostname entry to /etc/hosts

127.0.0.1 [myservername]
Set hostname or reboot

sudo hostname [myservername]

I faced the Same Issue and it is resolved by following steps.
1.Edit the HostNames File in your Ubuntu system
$ sudo nano /etc/hosts
After this add System name or Your System IP in first Name like following.
127.0.0.1 bflesgwks011
(Or)
127.0.0.1 192.168.15.22
2.Save&Exit the file.
3.Restart the Network by using the command.
$ sudo /etc/init.d/networking restart

I hope it Works.
thanks.
