Thanks for the reply guys.
I forgot to mention that /etc/hosts was having the ip to dns mapping and
Yes, i deliberately used IP address in the configuration because i thought
that if i use host-name then how would hadoop know about the network
interface on which it is supposed to run. In the initial configuration i
have used hostname only.
Here is the content of /etc/hosts file:
172.18.164.52 ihub-namenode1 # Added by NetworkManager
127.0.0.1 localhost.localdomain localhost
::1 ihub-namenode1 localhost6.localdomain6 localhost6
I *fixed this problem* by commenting the line highlighted above in red in
/etc/hosts file. This is a work around. Now, i will have to comment that
line everytime whenever system reboots or network service is restarted.
Does anyone knows a standard way to stop system updating /etc/hosts file?
