Haohui Mai commented on HDFS-5317:
----------------------------------
There are no obvious reasons that the sleep is required. Because the JSP page
runs in a different thread, the information is never guaranteed to be
up-to-date, in which case putting a sleep() in the JSP page would not help.
Alternatively, we can make the page faster, and the user always has the freedom
to refresh the page when needed.

> Here is how to reproduce this problem:
> # Goto https://namenode:https_port/dfshealth.jsp
> # Click on "Live Nodes" link
> # On the Live Nodes page, click one of the links for the datanodes. This link
> has always hardcodes the http link instead of http/https based on the context
> of the webpage.
> On datanode webUI page, the link "Go back to DFS home" does not work.
