Varun Saxena commented on YARN-4517:
------------------------------------
[~gtCarrera9], as per discussion with Wangda, unification of app/container
information, we can do after this branch goes into trunk. I think we can
definitely unify and have a single container page. I will do this later as part
of another JIRA. NM single app page, will have to see.
Regarding this,
bq. 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.
In old UI, we did not show anything if node was shutdown. So here, the change
is that we are showing even the nodes which have been SHUTDOWN. Just thought
that this might be useful info for the admin.
Now, some information regarding on which path, user can check the logs may be
useful but currently this information is not available in RM. I am not sure how
NM can report this to RM. You can report it in node registration but do we need
to ?
Ambari may have this information because I guess it knows exactly where
installation has been done through it.
Regarding node labels, we can add it in REST response indicating if labels are
enabled or not. We can do this later because this would require another JIRA
for REST changes.
500 error I think you are encountering on app page. I will fix it while doing
AM pages or as a separate JIRA.
