New to Hadoop-SSH communication
Hello,
I am new to Hadoop and trying to install multinode cluster on ubuntu VM's.I
am not able to communicate between two clusters using SSH.
My host file:
127.0.1.1 Master
127.0.1.2 Slave
The following changes i made in two VM's
1.Updated the etc/hosts file in two vm's
on Master VM
i did SSH keygen and trying to copy the key into Slave
ssh-keygen -t rsa -P ""
cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys
ssh-copy-id -i $HOME/.ssh/id_rsa.pub slave@ubuntu.
When i login into master and slave and check
master@ubuntu>Hostname it says UBUNTU
slave@ubuntu>Hostname it says UBUNTU
Could you assist me on this?
Thanks
Annt

Re: New to Hadoop-SSH communication
Posted by Mohammad Tariq <do...@gmail.com>.
ssh is actually *user@some_machine *to *user@some_other_machine*. either
use same username on both the machines or add the IPs along with proper
user@hostname in /etc/hosts file.
