I am trying to update the yarn scheduler queues through rest api and it does not seem to be working as I expect. I followed the example at the post: https://community.hortonworks.com/questions/33578/api-to-manage-yarn-capacity-queue.html but I keep getting the error 415 Unsupported Media Type.
Here is the command I am using:
curl -kv -u admin:admin -H "Content-Type: application/json" -H "X-Requested-By:ambari" -X PUT -d@yarn_queues.json https://<FQDN>:<PORT>/api/v1/views/CAPACITY-SCHEDULER/versions/1.0.0/instances/AUTO_CS_INSTANCE/reso...

Try using /var/lib/ambari-server/resources/scripts/configs.sh to update queue mapping(yarn.scheduler.capacity.queue-mappings) programmatically.
