Description

Hbase REST API, this interface `get 'version/cluster'`, when I use the header `Accept: application/json`, the response is not JSON but plain text.

    curl -X GET \
      -H "Accept: application/json" \
      "http://localhost:8888/version/cluster"

   "1.2.2"

But when I use `Accept: text/xml`, the response is correct XML.

    curl -X GET \
      -H "Accept: text/xml" \
      "http://localhost:8888/version/cluster"

     <?xml version="1.0" encoding="UTF-8" standalone="yes"?><ClusterVersion>1.2.2</ClusterVersion>
