HDFS SSL hdfs-site.xml https property substitute for dfs.secondary.http.address

I configured ssl for hdfs. I have an alert in the ambari console that related to the secondary namenode http address port 50090. Connection failed to http://wawf-wk-hadoop2.caci.com:50090 (). Is there an alternatate https property in hdfs-site.xml for dfs.secondary.http.address.

@Jack Madden

Are you talking about the following two parameters?

dfs.namenode.secondary.https-address (50091) => The secondary namenode HTTPS server address and port.
dfs.namenode.secondary.http-address (50090) => The secondary namenode http server address and port.

Reference: https://hadoop.apache.org/docs/r2.7.3/hadoop-project-dist/hadoop-hdfs/hdfs-default.xml

Those properties can be added to "Customer hdfs-site" using "Add Property" option via Ambari:

Ambari UI --> HDFS --> Configs --> Advanced -->  "Customer hdfs-site" --> "Add Property ..." (click)

That worked. Thank you very much. I'm going to look for the documentation listing all the available properties.
