> Ambari responds with a *Content-Type:text/plain* when the content is actually JSON.
> And the API only accepts (PUT/POST) JSON content, but fails when "Content-Type:application/json" is used.
> This breaks most HTTP/Restful clients, including the Knox UI proxy.
> Here is a GET showing JSON content with the wrong "Content-Type" (with some headers redacted):
> {code}
> $ curl -i http://localhost:8080/api/v1/clusters
> HTTP/1.1 200 OK
> Content-Type: text/plain
> {
>   "href" : "http://localhost:8080/api/v1/clusters",
>   "items" : [
>     {
>       "href" : "http://localhost:8080/api/v1/clusters/clustername",
>       "Clusters" : {
>         "cluster_name" : "clustername",
>         "version" : "HDP-2.4"
>       }
>     }
>   ]
> }
> {code}
> Attempt to send JSON with Content-Type:application/json fails and it although it responds with JSON data, it says its "text/plain".
> {code}
> $ curl -v -u admin\
>   -H "Content-Type: application/json" -H x-requested-by:useless \
>   http://localhost:8080/api/v1/stacks/HDP/versions/2.4/recommendations -d @temp.json
> < HTTP/1.1 500 Server Error
> < Content-Type: text/plain; charset=ISO-8859-1
> {
>   "status": 500,
>   "message": "Server Error"
> }
> {code}
> It accepts JSON with Content-Type:text/plain:
> {code}
> $ curl -v -u admin\
>   -H "Content-Type: test/plain" -H x-requested-by:useless \
>   http://localhost:8080/api/v1/stacks/HDP/versions/2.4/recommendations -d @temp.json
> > POST /api/v1/stacks/HDP/versions/2.4/recommendations HTTP/1.1
> > Content-Type: test/plain
> < HTTP/1.1 200 OK
> < Content-Type: text/plain
> {
>   "resources" : [
>     {
>       "href" : "http://localhost:8080/api/v1/stacks/HDP/versions/2.4/recommendations/8",
> ... snipped the rest of the JSON since it's not needed ...
> {code}
> This is the file that was sent:
> {code}
> $ cat temp.json
>     {
>       "recommend" : "configurations",
>       "services" : [ "AMBARI_METRICS","HDFS","HIVE","MAPREDUCE2","PIG","TEZ","YARN","ZOOKEEPER" ],
>       "hosts" : [ "ip-10-0-1-159.ec2.internal","ip-10-0-1-31.ec2.internal","ip-10-0-1-32.ec2.internal","ip-10-0-1-33.ec2.internal" ]
>     }
> {code}
