I have upgraded to Elasticsearch 2.0 and the new config doesn't have a setting for master and data nodes. Do I just add this in or am missing something?

Thanks,  
Michael

Perhaps this recent thread is helpful:

> [@Dedicated master nodes in Elasticsearch 2.0](https://discuss.elastic.co/t/dedicated-master-nodes-in-elasticsearch-2-0/33485):
>
> 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.

I'm also updating the docs to make this clearer.
