"Generating Go from JSON data" idea from me (ming-der wang) is already public and start implement since Aug. 3, 2015 (at least as early)

I claim the following idea is already on public since I had share or public in any social networks. "Generating Go from JSON data" is the key concept of gogetDB or my current database as service project (onion, demo-onion, ginger, pepper, chilli, and so on.) since 2 month ago (10/1/2015) of https://hackpad.com/Project-2-Product-Description-9iPxzxUeewK all source code are in github (before Oct. 1, 2015), start not to open in additional parts. the concept is implemented and demo in https://prezi.com/0lrgdih96_aw/copy-of-932015-gcpugtw-free-talk-kubernetes/ on Sept. 3, 2015 also public the way to do it in https://hackpad.com/GCPUG.TW-932015-live-demo-mGYQk3BWynb The presentation of this concept actually in Sept. 3, 2015 NTU hackathon, I already present it to public. Also named it "Give me JSON, I will give you an EndPoint (back)" All copyright belong to Ming-der Wang. log4analytics.com log4security.com

Kibana: This version of Kibana requires Elasticsearch 1.4.0 or higher on all nodes. I found the following incompatible nodes in your cluster: Elasticsearch 1.1.1 @ inet[/10.0.2.15:9301] (172.16.255.250)

If your Kibana 4.0 complains with your elasticsearch version 1.1.1. Even though you has install elasticsearch 1.4.2.  It's because an elasticsearch running embedded in logstash 1.4.2 (under vendor/jar/elasticearch-1.1.1). You should disable it if you install another elasticsearch 1.4.2 on the same or a different node.

This is a way to verify it (as follow)
