Robert Joseph Evans commented on HADOOP-7532:
---------------------------------------------
Web services is one thing, and the GUI is something else entirely, especially
for the Application Master. Web services are good and they often make writing
a dynamic web GUI much simpler, but having them does not change my original
question. Should be supporting a GUI *ON* the Application Master at all?
Having a GUI run on a separate box from the AM (even on a Gateway if the user
wants to have new and innovative visualizations) I think keeps our priorities
straight and offers a lot of flexibility. I would much rather see a full
featured API over a full featured GUI. I don't want to have to write something
that is brittle to pull data out of html when I could call a simple API/web
service to get it. I also would prefer not to have to go to two sources to get
the information we need, but that is a comment that should probably go on
MAPREDUCE-2863. I am not anti GUI. I just think that jumping through a bunch
of hoops, especially security hoops, to get the GUI to work seems like a lot of
effort that I would rather see put into making an API (or web service) that has
all of the functionality needed to support Hadoop's users and provide a simple
GUI that can be extended later to be more full featured.

> People have expressed interests of bringing Hadoop web UI up to date with the
> lightweight embedded web mvc framework used in MAPREDUCE-279 (cf.
> MAPREDUCE-2399). This is the umbrella jira for UI improvement for 0.23+.
> Individual items like web framework refactor/move and the unique challenge
> for MR2 webapp security will be filed separately.
> Thoughts/ideas on various improvement of Hadoop web UI are welcome here. Some
> of the ideas will naturally become sub-issues.
