> 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.
