Setting master and data node after upgrate to 2.0

[mgirndt (Michael)]

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

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) However, based on this documentation, 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.
