Andrew Wang commented on HDFS-5333:
-----------------------------------
Cool, thanks for working on this. IIRC, we are using some MVC library for the
webuis, but it's probably better characterized as a misuse. It'd be great to
see some love here.
[~cmccabe] has mentioned to me he'd like an actual REST API used to construct
the webui, because then you can easily build up other tooling that doesn't
involve scraping HTML. Maybe this is also possible with JMX (I'm not that
familiar with JMX beyond the /jmx page), but it'd be good to only pull the
necessary information rather than the all of /jmx when forming the webui.
One other note is that Hadoop clusters are often run on internal networks
without outside access to the internet, so I think you still need to serve
resources like Bootstrap and jQuery yourself. I don't think it's much of a
review headache either, personally I'm okay just comparing md5sums with a known
release to verify.
Also, as per commentary on HDFS-4670, cross-browser support is important (as
well as mobile). That's one thing that can't be faulted about the current UI:
plain HTML is very lightweight and renders ok everywhere :)
