Custom Domain with Hadoop Cluster?

I'm working on a research project and I currently own a domain (let's call it abc.xyz). I have purchased it on NameCheap and have some basic HTML/CSS/JavaScript running at the domain name (i.e. http://abc.xyz/index.html).

What I would like to do is use that same domain's sub-domains to be the FQDN for the Hadoop's domain, such that the master host would be master.abc.xyz and slaveX (where X is a number 1, 2, 3...) host would be slaveX.abc.xyz. What are the steps I must take to achieve this configuration? Will I have to give up hosting through NameCheap's cPanel?

In the control panel for your domain host you should find the option to add either A and or CNAME records to your existing domain abc.xyz.

As you have indicated you have IP addresses for each Hadoop instance then you could add A records along these lines;

master A <IP of master instance>
slave1 A <IP of slave 1>
slave2 A <IP of slave 2>

You also have the option of using CNAME records which are simply and alias for the existing domain name your Hadoop instances have.

master CNAME <fqdn of instance>
slave1 CNAME <fqdn of instance>
slave2 CNAME <fqdn of instance>

Once you have made your changes remember to increment your zone serial number (presuming the control panel doesn't do it for you.) wait a short time then your changes should propagate and allow you to access your instances via your own domain name.

If you need further help please post a comment & I can update my answer for you.
