        BTW, the correct parameters to use in HA mode for NameNodes is .clusterid.nnid, while HDFS federation uses .nnid. Instead of causing extra confusion, I simply attach the links to the corresponding documentation.

        Thanks Akira Ajisaka for the feedback!
        I checked yarn-default.xml as well as the implementation, TimelineServer does not respect HTTP_AND_HTTPS, so I updated the docs to correct it.

        I also updated the SecureMode doc to point to NameNode HA and ResourceManager HA docs. Interestingly, if HDFS is in federation mode, there are different set of parameters (actually seems incompatible with HA mode). So I included the link to that doc as well.

        Akira Ajisaka Please review again, thank you!

        Thanks Wei-Chiu Chuang for creating the patch. I have three comments:
        1.

        SecureMode.md
        To enable SSL for web console of HDFS daemons, set `dfs.http.policy` to either `HTTPS_ONLY` or `HTTP_AND_HTTPS` in hdfs-site.xml.
        
        To enable SSL for web console of YARN daemons, set `yarn.http.policy` to `HTTPS_ONLY` in yarn-site.xml.
        
        To enable SSL for web console of MapReduce JobHistory server, set `mapreduce.jobhistory.http.policy` to `HTTPS_ONLY` in mapred-site.xml.
        

        The patch says HTTP_AND_HTTPS does not work in MapReduce JHS and YARN daemons, which contradicts TimelineServer.md.

        TimelineServer.md
        Note that the selection between the HTTP and HTTPS binding is made in the `TimelineClient` based
        upon the value of the YARN-wide configuration option `yarn.http.policy`; the HTTPS endpoint will be
        selected if this policy is either of `HTTPS_ONLY` or `HTTP_AND_HTTPS`.
        

        If the patch is right, we should fix TimelineServer.md as well.

        2. The patch need to be rebased.
        3. Would you document that "dfs.namenode.https-address" and "yarn.resourcemanager.webapp.https.address" are the parameter for non-HA? In HA environment, we need <nn_id>/<rm_id> after the parameters.

        Rev02: more updates. At some point back in time, dfs.https.port was removed. Also, added https port for journal nodes.
