Sean Roberts updated AMBARI-9016:
---------------------------------
Description:
Ambari responds with a *Content-Type:text/plain* when the content is actually
JSON.
Also, API does not accept the "Content-Type:application/json" even though it
expects the content of the PUT/POSTS to be JSON.
This breaks most any HTTP/Restful client, including the Knox UI proxy.
Here is a GET (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-2.6"
}
}
]
}
{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

{
"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
