Well, that was a tough one.

Here's what fixed it:

Per http://enable-cors.org/server_apache.html, in /etc/apache2/httpd.conf, configure Access-Control-Allow-Origin:

    # Add the following line to enable CORS to connect to local elasticsearch.
    Header set Access-Control-Allow-Origin "localhost:9200"
    AllowOverride none
    Require all denied

Per https://jsbroadcast.com/elastic-search-cors/, in elasticsearch-1.7.0/config/elasticsearch.yml add:

http.cors.enabled : true // 
http.cors.allow-origin: "/.*/"
http.cors.allow-methods : OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers : "X-Requested-With,X-Auth-Token,Content-Type, Content-Length, Authorization"

I can now run the client.ping call without any error.
