Description

Alerts for services that support a standard HA mode (nameservice and/or alias) need to be able to understand how to calculate the correct server to contact. This means building a dynamic key to use when discovering the URL to use for METRIC and WEB alerts.

The proposal is to add a new child element to the URL parameter:

"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}}}}"
