Setting up on localhost (Optional)

Chunkservers and master will not work with each other if running on the same IP address, so we need to make sure that they can (You can skip this if you are not running chunkservers on the same IP address as master.)

First, add an identifier to for master 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.
