Review request for Ambari, Alejandro Fernandez and Nate Cole.
Bugs: AMBARI-9848
https://issues.apache.org/jira/browse/AMBARI-9848
Repository: ambari
Description (updated)
-------
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:
{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}
*** NameNode Process was removed because it was a redundant check already
covered by the web client check ***

Testing
-------
Deployed a cluster to ensure that existing alerts did not break. Upgraded to
HDFS HA mode and then took down each NN one at a time to verify correct alerts
triggered.
