Vinay commented on HDFS-5312:
-----------------------------

I have verified this with HDFS-3405, uploading of fsimage with HTTPS_ONLY is 
success. 
Without HDFS-3405 it fails because SNN doesnot have HTTPS and NN tries to 
access http port with https scheme. Anyway this will no more exist if HDFS-3405 
 goes in.

Thanks Hauhui Mai and Jing.

> DFSUtil#getInfoServer() returns only the authority (i.e., host+port) when 
> searching for the http / https server. This is insufficient because HDFS-5536 
> and related jiras allows NN / DN / JN to open HTTPS only using the HTTPS_ONLY 
> policy.
> This JIRA addresses two issues. First, DFSUtil#getInfoServer() should return 
> an URI instead of a string, so that the scheme is an inherent parts of the 
> return value, which eliminates the task of figuring out the scheme by design. 
> Second, it introduces a new function to choose whether http or https should 
> be used to connect to the remote server based of dfs.http.policy.
