             Summary: Clean up the HTTP-related configuration in HDFS
                 Key: HDFS-5321
                 URL: https://issues.apache.org/jira/browse/HDFS-5321
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Haohui Mai
            Assignee: Haohui Mai


Currently there are multiple configuration keys that control the ports that the NameNode and DataNode listen to, and the default ports that the hftp/webhdfs clients are connecting to.

Below is a quick summary of these configuration:

|| Keys || Description ||
| dfs.namenode.http-address | The address that the namenode http server binds to |
| dfs.namenode.https-address | The address that the namenode https server binds to |
| dfs.http.port | The default port that the hftp/webhdfs client use to connect to the remote server|
| dfs.https.port | The default port that the hsftp client use to connect to the remote server|

I propose to deprecate dfs.http.port and dfs.https.port to avoid potential confusions (e.g., HDFS-5316). Note that this removes no functionality, since the users can specify ports in hftp / webhdfs URLs when they need to connect to HDFS servers with non-default ports.
