accessing variable names in Ambari through REST

[#1]

How can I list the existing variable names and their values used across various configurations of Ambari through REST API for example {{namenode_heapsize}} ?

You can use the below call which will list all the values for that specific service :

http://<Ambari-hostname>:8080/api/v1/clusters/<cluster-name>/configurations/service_config_versions?...

Thanks @krajguru, that was exactly I was looking for 🙂

@nyadav To add to @krajguru's answer:

You can use query parameter is_current=true to retrieve the latest configuration version in case you have multiple versions of configurations.

E.g

http://<Ambari-hostname>:8080/api/v1/clusters/<cluster-name>/configurations/service_config_versions?...
