Perhaps this recent thread is helpful:

> Prior to elasticsearch 2.0, you have to specify node.data = false and node.master = true to set dedicated master nodes. (Refer to this [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/1.7/modules-node.html)) However, based on this [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/2.0/modules-node.html), node.master setting is no longer available. Only node.data still exists. How do set dedicated master nodes in Elasticsearch 2.0? Thank you.
