Li Lu commented on YARN-4517:
-----------------------------

Thanks for the work [~varun_saxena]! Some comments from my side:

One main question: maybe we want to unify all application/container views? I 
noticed that right now, the "application views" from the application list and 
from the NM are different. Ideally, we'd like to provide one unified place to 
show one application, no matter the user arrives from the app list, flow list, 
NM app list or anywhere else? We can also integrate Similar story also applies 
to the container view? 

Meanwhile, maybe it's time to start detailed page style designs. With unified 
app/container views, we need to address questions like where to put node id/app 
ids in the page, and how to organize all available data on the page? 

I noticed one workflow related problem: once a NM is in shutdown state, it is 
not possible to go into the node page. What is the assumed debug workflow on 
this? What if a NM is down accidentally and the user is trying to look at the 
NM logs/detailed status to figure out what happened? 

On my local machine, links to application logs are broken with just a 500 
error. Maybe we can improve this in future. 

Seems like there's no need to show "node labels" if node label is not enabled? 

I'm not sure about the meaning of the row in node status showing "Node Health 
Report". This looks like some static content or the dynamic part is empty?
