Adding a custom services onto HDP stack

[Krishna Kishore Bonagiri]

Hi,
   I am trying to add a new custom service to my HDP stack. Added a new
directory for my custom service
at /var/lib/ambari-server/resources/stacks/HDP/2.1/services/SAMPLESRV,
created the metainfo.xml and the other required scripts. But the service
doesn't appear in the list of services through Ambari.

I also tried to add the same through the following curl command, and
getting a Bad Request like below. Please see if you can help.

[root@datanode5 resources]# curl -u admin:admin -i -X POST -d
'{"ServiceInfo":{"service_name":"PX_SAMPLESRV"}}'
http://9.126.90.236:8080/api/v1/clusters/HadoopCluster/services
HTTP/1.1 400 Bad Request
Set-Cookie: AMBARISESSIONID=udr70j73sob4x1f5dmq93coi;Path=/
Content-Type: text/plain;charset=ISO-8859-1
Content-Length: 47
Server: Jetty(7.6.7.v20120910)

{
  "status": 400,
  "message": "Bad Request"
}

Thanks,
Kishore
