Hi
I am running cluster with few master and few data nodes.
I want to understand that following setting will only be required for Master nodes or it will require on every Data as well as Master nodes ?
discovery.zen.minimum\_master\_nodes: 3
gateway.expected\_data\_nodes: 6
gateway.recover\_after\_nodes: 2
gateway.recover\_after\_time: 8m
Thanks a lot.

required on all nodes.
All gateway settings are only required on master nodes (see also [reference docs](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/modules-gateway.html)).
