Subject Re: Connection Refused error on Hadoop-2.6.0 on Ubuntu 14.10 desktop running Pseudo Mode
Date Wed, 22 Apr 2015 09:00:36 GMT
Hi Anand,

comment the ip address - 127.0.1.1 in /etc/hosts
add the following ip address - 127.0.0.1  localhost  in /etc/hosts.

Restart your hadoop cluster after made changes in /etc/hosts

Regards,
