Need some advice.
I have a cluster ES 6.4.0 with 5 Data Nodes, 1 Master Node.
All of the 5 Data Nodes are Master elligible nodes.
Since i have a dedicated Master Node (no other role), I would like that this node becomes the Master Node whenever it is possible (otherwise, no reason to have dedicated Master).
Scenario: Dedicated MN goes down, then another node is elected MN. Fine. But when this dedicated master node comes back up, i would like that this node is elected Master Node.
I think that it is not possible to do that. Is there any reason ? Don't you think that could be an enhancement ?
