I'm on elasticsearch 6.0.0-rc2 and I've found I've not able to create an index with multiple types:

```auto
PUT twitter
{}

PUT twitter/_mapping/user 
{
  "properties": {
    "name": {
      "type": "string"
    }
  }
}

PUT twitter/_mapping/user2 
{
  "properties": {
    "name": {
      "type": "string"
    }
  }
}

```

Returns

```auto
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Rejecting mapping update to [twitter] as the final mapping would have more than 1 type: [user2, user]"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "Rejecting mapping update to [twitter] as the final mapping would have more than 1 type: [user2, user]"
  },
  "status": 400
}

```

This is expected as per [the list of breaking changes for Elasticsearch 6.0](https://www.elastic.co/guide/en/elasticsearch/reference/6.0/breaking-changes-6.0.html). You can read more about it in [this blog post](https://www.elastic.co/blog/index-type-parent-child-join-now-future-in-elasticsearch).
