Thanks, Rob. Changing to POST works fine!
I am now able to kerberize the cluster using the REST API. However. starting
services fails:
curl -H "X-Requested-By:ambari" -u admin:admin -i -X PUT -d '{"ServiceInfo":
{"state" : "STARTED"}}' http://localhost:8080/api/v1/clusters/MyCluster/services

{
"status" : 400,
"message" : "java.lang.IllegalArgumentException: Missing KDC administrator
credentials.\nThe KDC administrator credentials must be set in session by
updating the relevant Cluster resource.This may be done by issuing a PUT to the
api/v1/clusters/(cluster name) API entry point with the following payload:\n{\n
\"session_attributes\" : {\n \"kerberos_admin\" : {\"principal\" :
\"(PRINCIPAL)\", \"password\" : \"(PASSWORD)\"}\n }\n}"
}
I then issued the command as suggested by the above message:curl -H
"X-Requested-By:ambari" -u admin:admin -i -X PUT -d '{"session_attributes" :
{"kerberos_admin" : {"principal" : "fay/[email protected]", "password" :
"passw0rd"}}}' http://localhost:8080/api/v1/clusters/MyCluster
and then re-issued the start-service command. Still the start failed with the
same error message.
Many thanks for your patience and help!

Hi Fay...Instead of PUT, you should do a POST. To create a new
kerberos_descriptor artifact. If a kerberos_descriptor artifact already
existed, then you out PUT to update it.I'll have to check, is the documentation
I correct or confusing?RobOn Jan 7, 2016, at 6:50 PM, Fay Wang

Thanks, Rob, for the info!
I am able to get the default kerberos descriptor via REST api, but
get an error when issuing the following command to update the descriptor:
