Yes, some of the bits may already be available to you as charms, others
you will need to write as charms yourself, and I would encourage you
to submit them to the "charm store" so people can collaborate on them
with you.

I'd recommend joining the IRC channel #juju on Freenode as you work on
this, as there are quite a few helpful people there who can walk you
through the early steps.

Some good places to start:

https://juju.ubuntu.com/Charms
https://juju.ubuntu.com/docs/write-charm.html

I think you will probably need just two charms:

1) cluster head node(s?)
2) slave nodes

You might want to look at the hadoop charms for some inspiration.

Also, Welcome!
