Do people normally combine these two processes onto one machine? Currently I
have them on separate machines but I am wondering they use that much CPU
processing time and maybe I should combine them and create another DataNode.
It depends on the size of your cluster. I think you can combine them
together if your cluster has less than 10 machines.

I think it is definitely not a good idea to combine these two in production
environment.

I have a cluster of 4 machines plus one machine to run nn & jt. I
have heard that 5 or 6 is the magic #. I will see when I add the next
batch of machines.
And it seems to running fine.
