How to slowly decomission a master node?

Our hadoop baby has been growing and our main node is now more of a drag to our cluster than anything else.

For multiple reasons I can't just get rid of it but would like to leave it as the "director" to launch jobs in BUT w/o taking any M/R slots.

Is this possible? Can you manually assign zero M/R to your master without taking away its ability to launch jobs and pass tasks to the nodes?
