when ES use default config, kibana start print the following error:  
{"name":"Kibana","hostname":"ubuntu","pid":14260,"level":60,"err":{"message":"unknown error","name":"Error","stack":"Error: unknown error\n at respond (/opt/kibana/src/node\_modules/elasticsearch/src/lib/transport.js:237:15)\n at checkRespForFailure (/opt/kibana/src/node\_modules/elasticsearch/src/lib/transport.js:203:7)\n at HttpConnector.

_I debug with node-inspector, find kibana use client.ping to test whether ES is alive.(HEAD [http://localhost:9200](http://localhost:9200))._  
_But ES-2.1.1 respond HEAD with empty string ""._

That is correct, Kibana 4.1 does not support Elasticsearch 2. If you want to use Elasticsearch 2.1, you'll need to use Kibana 4.3.

See the support matrix for more detail: [https://www.elastic.co/support/matrix#show\_compatibility](https://www.elastic.co/support/matrix#show_compatibility)
