1 Master node: Low RAM and CPU machine
2 Coordinating nodes (also eligible masters): Highly configured machines
2 Data nodes (One Replica)(RAID-0)
By the master election process, any of the Master or my coordinating nodes is elected as active master.
I send all my indexing and searching requests to both coordinating nodes.
If coordinating node is elected as master, it starts performing 2 responsibilities, one is master and other is coordinating.
Is there an option to tell ES explicitly that my 'Master node' above should be the initial active master, when my cluster starts. And thereafter it may give priority to any of coordinating nodes ??
This way initially, unless there is problem with 'Master node', at least my master responsibility will be carried out by dedicated master node and coordinating responsibility will be with Coordinating nodes.
