Subject [jira] [Created] (AMBARI-10505) Equals predicate does not work for host component metrics
Date Wed, 15 Apr 2015 20:15:59 GMT
Siddharth Wagle created AMBARI-10505:
----------------------------------------

             Summary: Equals predicate does not work for host component metrics
                 Key: AMBARI-10505
                 URL: https://issues.apache.org/jira/browse/AMBARI-10505
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 2.1.0


Generally equals predicate works on the host components. For example below API works
{code}

{
  "href" : "http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/services/HDFS/components/NAMENODE?host_components/HostRoles/host_name=c6401.ambari.apache.org",
  "ServiceComponentInfo" : {
    "cluster_name" : "c1",
    "component_name" : "NAMENODE",
    "service_name" : "HDFS"
  },
  "host_components" : [
    {
      "href" : "http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/hosts/c6401.ambari.apache.org/host_components/NAMENODE",
      "HostRoles" : {
        "cluster_name" : "c1",
        "component_name" : "NAMENODE",
        "host_name" : "c6401.ambari.apache.org"
      }
    }
  ]
}
{code}

*But while using equals predicate with the host_component metrics it is not working.* GET
request on following API does not return anything.
{code}
http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/services/HDFS/components/NAMENODE?host_components/metrics/dfs/FSNamesystem/HAState=active
{code}

NOTE: filtering does work for host components metrics i.e below API call works: 
{code}http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/services/HDFS/components/NAMENODE?fields=host_components/metrics/dfs/FSNamesystem/HAState

{code}
