YUBI LEE updated HADOOP-18585:
------------------------------
Description:
After HADOOP-16314, WebServlet.java was added. On WebServlet#doGet, it
redirects '/' to '/index.html'. However, if a client connects to DataNode with
https scheme, it fails to connect because it responds 302 with Location header
which has http scheme.
(Hostname is modified.)
{code:java}
$ curl https://dn1.example.com:50475/ -v 2>&1 | grep Location
< Location: http://dn1.example.com:50475/index.html
{code}
I can't ensure that which solution is the best among:
- Use DefaultServlet instead of WebServlet. DataNode can answer with index.html
when accessed in '/'.
- According to "dfs.http.policy" in hdfs-site.xml, run internal infoserver as
https or http server each.
- Make redirection on URLDispatcher.java
