--------------------------------------

             Summary: Enable NN Web Alerting with Multiple Namservices
                 Key: AMBARI-15508
                 URL: https://issues.apache.org/jira/browse/AMBARI-15508
             Project: Ambari
          Issue Type: Bug
    Affects Versions: trunk
            Reporter: Henning Kropp


If dfs.namenode.http(s)-address is removed due to HA and multiple nameservices are configured
NN web alerting reports NN site down.

Reason seems to be the following alerting configuration:
{code}
"high_availability": {
              "nameservice": "{{hdfs-site/dfs.nameservices}}",
              "alias_key" : "{{hdfs-site/dfs.ha.namenodes.{{ha-nameservice}}}}",
              "http_pattern" : "{{hdfs-site/dfs.namenode.http-address.{{ha-nameservice}}.{{alias}}}}",
              "https_pattern" : "{{hdfs-site/dfs.namenode.https-address.{{ha-nameservice}}.{{alias}}}}"
            }
{code}
