I am following this tutorial :
I am using Raspberry Pi 3. When I tried to test SSH connection same like the tutorial, I am getting:
ssh: connect to host hadoopmaster port 22: No route to host
Also I don't know if the file /etc/network/interfaces is the right file to put my network configuration :
iface eth0 inet static address 192.168.0.110 netmask 255.255.255.0 gateway: 192.168.0.1
because It is empty and when I put the IPs in it, I can't connect to wifi anymore.
I tried also to put the static IP cofiguration inside /etc/dhcpcd.conf and I am getting the same above error when I try to open ssh connection.
I also added a host name and IP to /etc/hosts , which is not mentioned in the tutorial, but nothing worked.
