             Summary: Ambari API add rack info to HDFS service component fields
                 Key: AMBARI-24144
                 URL: https://issues.apache.org/jira/browse/AMBARI-24144
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
    Affects Versions: 2.6.0
         Environment: HDP 2.6
            Reporter: Hari Sekhon


Improvement Request to add rack information to the HDFS service DATANODE components endpoint:

[https://github.com/apache/ambari/blob/trunk/ambari-server/docs/api/v1/components-component.md]

I know rack info can be obtained from the hosts API but that is not limited to datanodes, it returns all nodes including edge nodes.

I wrote [check_ambari_cluster_hdfs_rack_resilience.py|https://github.com/HariSekhon/nagios-plugins/blob/master/check_ambari_cluster_hdfs_rack_resilience.py] Nagios Plugin against that API but it might be better if it didn't enforce this against even edge nodes as there is no datanode running so it's not really relevant, and the alternative is less efficient multiple calls to the API.
