Ok, I have found a solution.
First of all, for some bug in Ambari I have to use raw body format and no
json.
So I have changed the body_format to json and appended "Content-Type":
"text/plain" to the headers parameter.
Now my headers parameter looks like:
headers: '{"X-Requested-By":"ambari", "Content-Type":"text/plain"}'
Now everything works properly.
Hi all!
