Setting up network on localhost (Optional)
While master/chunkserver will work with each other if running on the same IP address, it's best to assign master it's own dedicated IP.
First, add an identifier for sfsmaster
in the /etc/hosts file:
10.33.33.33 sfsmaster
It can be any IP address, but preferably it should be something private and unused.
Next, add the new IP address to your loopback device
sudo ip a a 10.33.33.33 dev lo
Note that a loopback will significantly impact performance. However, you shouldn’t use localhost for production anyway. This will apply temporarily until the next boot.
