Hi Fay…
The REST API call to set the KDC administrator credentials is to use
the/api/v1/clusters/$CLUSTER_NAME entry point, not the
/api/v1/clusters/$CLUSTER_NAME/service entry point. So you need to make 2 API
calls – one to set the credentials and one to start the services. Ideally you
should set the cookie files for curl to ensure you use the same session – but
that may not be necessary depending on the version of Ambari you are using. To
set the cookie files for curl, use
-b <path to cookie file> -c <path to cookie file>
For example:
curl -c /tmp/cookies.txt -b /tmp/cookies.txt -k -H 'X-Requested-By:ambari' -u
admin:$ADMINPASS –i –X PUT –d @/tmp/set_credentials.json
$AMBARI_SERVER_HOST_PORT/api/v1/clusters/$CLUSTER_NAME
curl -c /tmp/cookies.txt -b /tmp/cookies.txt -k -H 'X-Requested-By:ambari' -u
admin:$ADMINPASS -i -X PUT -d '{"ServiceInfo": {"state" : "STARTED"}}'
$AMBARI_SERVER_HOST_PORT/api/v1/clusters/$CLUSTER_NAME/services
I hope this helps,
Rob

Subject: can not start service after kerberos
Hi, We got a very weird problem and desparetely need help! We want to
start services after kerberos is enabled. The following API failed with
"Missing KDC administrator credentials":
(1) curl -k -H 'X-Requested-By:ambari' -u admin:$ADMINPASS -i -X PUT -d
'{"ServiceInfo": {"state" : "STARTED"}}'
$AMBARI_SERVER_HOST_PORT/api/v1/clusters/$CLUSTER_NAME/services

updating the relevant Cluster resource.This may be done by issuing a PUT to the

\"session_attributes\" : {\n \"kerberos_admin\" : {\"principal\" :
\"(PRINCIPAL)\", \"password\" : \"(PASSWORD)\"}\n }\n}"
(2) We then provided KDC administrator credential:
curl -k -H 'X-Requested-By:ambari' -u admin:$ADMINPASS -i -X PUT -d
@/tmp/start_services.json
$AMBARI_SERVER_HOST_PORT/api/v1/clusters/$CLUSTER_NAME/services
The content of /tmp/start_services.json is:

"session_attributes" : {
"kerberos_admin" : {
"principal" : "admin/[email protected]",
"password" : "P@ssw0rd"
}
}
}
It again failed with "unsupported properties":

}
Please let us know how to make it work...Any help is highly appreciated...
