I am still not able to communicate between two Vm's. Changed the hostname as Master and Slave.Copied the hostnames in master slave etc/hosts.reinstalled SSH server.
But when i try to copy the file from master to slave its copying to the master and not to the slave scp -r /usr/local/hadoop/conf hduser@slave:/home/hduser/Downloads/Somethings Master etc/hosts # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 127.0.0.2 slave 127.0.0.3 master Slave etc/hosts #127.0.0.1 localhost # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 127.0.0.2 slave 127.0.0.3 master am i missing anything..Thanks in advance..
