Li Lu commented on YARN-4517:
-----------------------------
Hi [~varun_saxena], sorry about the late reply. With regard to the
app/container pages, I'm actually fine to have the current page as a
placeholder, but just would like to make sure eventually we will have unified
app/container pages. This said, I do not really care if the container page for
nodes shows correct info or just the (only) yarn container page which shows
some placeholder right now. Just don't want to distract you to build separate
container/app pages.
All other issues are rather minor as of now. If they're easy to fix, then feel
free to change them. Otherwise, I'm fine with moving forward with the code
infra built up for now. My only concern is on the logs: right now we don't have
a way to land on the NM's webpage if the NM is down, so there's no way we can
look at the NM logs for the crashed ones through webapp. However, in the new
UI, when the node is shutdown, I just could not hold myself to try to find a
link to the NM logs to figure out why. I think the workflow here changed
slightly, hence the user experience. Some other projects like Apache Ambari may
want to maintain those information as well, but in YARN, it will be great if we
could provide our users a way out. Maybe something like: "You have to ssh to
the missing nodes' xxxx/xxx/ dir to look for the logs" would even be helpful.
