Ambari REST API list components with Stale configs not showing service_name

avatar

I would like to list all components with stale configs and I would like to have the service_name in the response. I tried several methods, like the one below, and all I get is the component but not the service it belongs to. Any idea how to get this please?

I am using Ambari 2.1

curl -u admin:admin http://host_name:8080/api/v1/clusters/test_cluster/host_components?HostRoles/stale_configs=true

Currently i do not have Ambari 2.1 setup ready to test the same .... but i guess it should be working as expected or else it might be enhanced to show the service name in later version of ambari 2.1

So, I am getting mixed results. When I use the browser, like what you did above, I get the service_name. But when I use curl on command line, I do NOT get the the service_name. Which makes me more confused.

I am using Ambari 2.1

I upgraded to Ambari 2.4.2 and the same issue. In order to replicate the issue, you need to call that url using curl and not the browser. Something like:

curl -u admin:admin -H "X-Requested-By:ambari" -X GET http://localhost:8080/api/v1/clusters/Sandbox/host_components?HostRoles/stale_configs=true&fields=Ho...

@Theyaa Matti

Can you try putting the URL inside Quotation Mark?

As the URL consist of (&)

Example:

curl -u admin:admin -H "X-Requested-By:ambari" -X GET "http://172.26.102.21:8080/api/v1/clusters/hdp234/host_components?HostRoles/stale_configs=false&fields=HostRoles/service_name

I tried your suggestion and here is what I get:

"HostRoles" : {

"cluster_name" : "test_cluster",

"component_name" : "WEBHCAT_SERVER",

"host_name" : "hostname",

"stale_configs" : true

}

So, no service_name 😞
