Haohui Mai updated HDFS-5312:
-----------------------------
Description:
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.
was:
DFSUtil#getInfoServer() returns only the authority (i.e., host+port) when
searching for the http / https server.
The task of figuring out which scheme that the authority supposes to use.
Unsurprisingly, the task is cumbersome, and the code performs the task in an
inconsistent way.
This JIRA proposes to return an URI object 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.
> Refactor DFSUtil#getInfoServer to return an URI
