How to know the configuration type for parameter in ambari cluster by API

examples of configuration type - core-site, hdfs-site, mapred-queue-acls

lets say I want to find the configuration type for the parameter - "mapreduce.map.memory.mb” , in this case configuration type is mapred-site

from some reason I get - { "status" : 404, "message" : "The requested resource doesn't exist: Cluster not found, clusterName=plain_ambari" ( when I run this - curl -u admin:admin -H "X-Requested-By: ambari" -X GET http://ambarir02.urs.com:8080/api/v1/clusters/plain_ambari

[#3]

ok now I get all mapreduce.map.memory.mb parameters but not the config type ( I used grep to match them ) , still not get the config type for the parameter

[#4]

the main target is to find the config type because one of the script ( config.sh) arguments is the config type , so when we want to change the parameter value by the script we need the config type , but I not have the config type info , so how to know the config type when we want to change the parameter ?

[#5]

any new suggestion?
