Is it possible to make the cluster favor a node as it's master?


I have a small cluster built of 4 nodes which only 3 of them are data nodes. Currently, all four of them are master eligible which is of course not a very good idea because all the three nodes are busy handling their data. But since that I don't have an option to add two more nodes to the cluster, I would like to know if it is possible somehow to make the cluster choose the fourth node (which is configured as false) to be its master node and only when it's not available to choose another node randomly. Is that doable?

Thanks a lot,

No it is not.

You can make the fourth node as a client node and direct traffic there, instead of using the master node(s)
