While trying to merge conflicts given at [https://www.elastic.co/guide/en/elasticsearch/reference/2.3/indices-put-mapping.html#merging-conflicts](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/indices-put-mapping.html#merging-conflicts) I am getting the below error:

`{"error":{"root_cause":[{"type":"action_request_validation_exception","reason":"Validation Failed: 1: mapping source is empty;"}],"type":"action_request_validation_exception","reason":"Validation Failed: 1: mapping source is empty;"},"status":400}`  
When I curl -XGET of the mapping source it does not return empty. Any pointers?

Can you provide the exact commands you are passing to ES?
