Ambari REST API list components with Stale configs not showing service_name

theyaa — Mon, 08 May 2017 23:13:51 GMT

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

@Theyaa Matti

Have you tried the following approach?

http://erie1.example.com:8080/api/v1/clusters/ClusterDemo/host_components?HostRoles/stale_configs=true&fields=HostRoles/service_name

And also a bit more extended format as following:

http://erie1.example.com:8080/api/v1/clusters/ClusterDemo/host_components?HostRoles/stale_configs=true&fields=HostRoles/service_name,HostRoles/host_name&minimal_response=false

can you try this:

http://host_name:8080/api/v1/clusters/test_cluster/host_components?HostRoles/stale_configs=true&fields=HostRoles/service_name,HostRoles/state,HostRoles/host_name,HostRoles/stale_configs,&minimal_response=true

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 😞

Tried both methods and same results, no service_name 😞

@Theyaa Matti

Which ambari version are you using? Also can you please share the exact command and response output here?

I just now tried the same on Ambaei 2.4.0.0 and can se this thing working fine.

http://localhost:8080/api/v1/clusters/Sandbox/host_components?HostRoles/stale_configs=true&fields=HostRoles/service_name

@Theyaa Matti

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

Can you try this

http://172.26.100.103:8080/api/v1/clusters/hdp253/host_components?HostRoles/stale_configs=false&fields=HostRoles/service_name

see if you are able to list all service names, if yes, then change the value for "stale_configs=true" and rerun it like this

http://172.26.100.103:8080/api/v1/clusters/hdp253/host_components?HostRoles/stale_configs=true&fields=HostRoles/service_name

I am using HDP 2.6 and Ambari 2.5, works for me.

Here is the sample output:

{
  "href" : "http://172.26.100.103:8080/api/v1/clusters/hdp253/host_components?HostRoles/stale_configs=false&fields=HostRoles/service_name",
  "items" : [
    {
      "href" : "http://172.26.100.103:8080/api/v1/clusters/hdp253/hosts/xlnode-1.h.c/host_components/ACTIVITY_ANALYZER",
      "HostRoles" : {
        "cluster_name" : "hdp253",
        "component_name" : "ACTIVITY_ANALYZER",
        "host_name" : "xlnode-1.h.c",
        "service_name" : "SMARTSENSE",
        "stale_configs" : false
      },
      "host" : {
        "href" : "http://172.26.100.103:8080/api/v1/clusters/hdp253/hosts/xlnode-1.h.c"
      }
    },

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

@Theyaa Matti

Tried this with Ambari 2.2, of course I am checking for non-stale configs here, but it does show the service_name. You should upgrade your Ambari version, its not a major version.

http://172.26.102.21:8080/api/v1/clusters/hdp234/host_components?HostRoles/stale_configs=false&fields=HostRoles/service_name

Output

      "HostRoles" : {

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://172.26.102.21:8080/api/v1/clusters/hdp234/host_components?HostRoles/stale_configs=false&fields=HostRoles/service_name

@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

As simple as adding quotes!
