You need to put the URL in quotes as "&" is being treated as special character.


e.g. "http://ec2-xx-xx-xxx-xx.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/configurations?type=hdfs-site&tag=1"?

The response I get is this.
{
  "href" : "http://xxxxx.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/configurations?type=hdfs-site",
  "items" : [

Subject: Re: Service endpoints URLs using Ambari APIs

Thanks sumit for the quick reply.   Here is the output I received.  I don't see any http property
in the config .

I am using Ambari 2.0 version.

1)  Retrieve tag info.
 curl -u user:xxxxxx http://ambari-server-host.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/hosts/awsdcdpmn01.dpst.internal/host_components/NAMENODE?fields=HostRoles/actual_configs/hdfs-site
{
  "href" : "http://ambari-server-host.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/hosts/awsdcdpmn01.dpst.internal/host_components/NAMENODE?fields=HostRoles/actual_configs/hdfs-site",
  "HostRoles" : {
    "cluster_name" : "dc",
    "component_name" : "NAMENODE",
    "host_name" : "awsdcdpmn01.dpst.internal",
    "actual_configs" : {
      "hdfs-site" : {
        "default" : "1"
      }
    }
  },
  "host" : {
    "href" : "http://ambari-server-host.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/hosts/awsdcdpmn01.dpst.internal"
  }


2) Get the config info.
curl -u user:xxxx http://ambari-server-host.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/configurations?type=hdfs-site&tag=1

 {
  "href" : "http://ambari-server-host.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/configurations?type=hdfs-site",
  "items" : [
    {
      "href" : "http://ambari-server-host.us-west-2.compute.amazonaws.com:8080/api/v1/clusters/dc/configurations?type=hdfs-site&tag=1",
      "tag" : "1",
      "type" : "hdfs-site",
      "version" : 1,
      "Config" : {
        "cluster_name" : "dc"
      }
    }
  ]
}

Unfortunately, there is no single API for this. You need to merge data from more than one
API


* API to get the host(s) where the service is deployed (e.g. http://ambari-server-host:8080/api/v1/clusters/c1/hosts/smc201-1.c.pramod-thangali.internal/host_components/NAMENODE?fields=HostRoles/actual_configs/hdfs-site<http://smc201-1.c.pramod-thangali.internal:8080/api/v1/clusters/c1/hosts/smc201-1.c.pramod-thangali.internal/host_components/NAMENODE?fields=HostRoles/actual_configs/hdfs-site>)

-- pick the tag for the actual config

* Get the config and grep the property (e.g. http://ambari-server-host:8080/api/v1/clusters/c1/configurations?type=hdfs-site&tag=version1436499674556<http://smc201-1.c.pramod-thangali.internal:8080/api/v1/clusters/c1/configurations?type=hdfs-site&tag=version1436499674556>)

-- pick the correct property (e.g. dfs.namenode.http-address)?

Subject: Service endpoints URLs using Ambari APIs

I am looking for an API that will provide all the service endpoints of the components that
are installed using Ambari


The api should return something like this.

ResourceManager Logs = http://hostname1:8088/
namenode  = http://hostname:50070<http://hostname:50070/>
oozie   =     http://hostname2:11000<http://hostname2:11000/>
It could be single API or multiple API call , anything is fine.

Is there any API does exists  ?
