Question:
Installing cosmos-gui

Description:
Can you help me with installing cosmos-gui? I think you are one of the developers behind cosmos? Am I right?
We have already installed Cosmos, and now we want to install cosmos-gui.
In the link below, I found the install guide:
https://github.com/telefonicaid/fiware-cosmos/blob/develop/cosmos-gui/README.md#prerequisites

Under subchapter “Prerequisites” is written

A couple of sudoer users, one within the storage cluster and another one wihtin the computing clusters, are required. Through these users, the cosmos-gui will remotely run certain administration commands such as new users creation, HDFS userspaces provision, etc. The access through these sudoer users will be authenticated by means of private keys.

What is meant by the above? Must I create, a sudo user for the computing and storage cluster? And for that, do need to install a MySQL DB?

And under subchapter “Installing the GUI.”

Before continuing, remember to add the RSA key fingerprints of the Namenodes accessed by the GUI. These fingerprints are automatically added to /home/cosmos-gui/.ssh/known_hosts if you try an ssh access to the Namenodes for the first time.

I can’t make any sense about the above. Can you give a step by step plan?

I hope you can help me.
