Reassign an elected master

Is there a best practice on reassigning an elected master? For example, if I need to take down that master for maintenance.

Thanks,

You should stop it gracefully using either the API or giving the
java process a TERM.

Easiest way is to run this from the cluster:

curl -XPOST localhost:9200/_cluster/nodes/_master/_shutdown

Make sure that if you have minimum_master_nodes set there are
enough leftover that the cluster can tolerate losing one of them.
