Henning Kropp commented on AMBARI-15508:
----------------------------------------
[~sumitmohanty] please do so. I simply did not feel comfortable doing all in
one ticket/step. Please also include AMBARI-15777.
AMBARI-15506 is updated.
At least the documentation for the alerts would also need an update. Should we
have a separated ticket for clean up of the documentation?
> Enable HDFS alerts with multiple namservices

> 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}
