Rohith commented on YARN-3273:
------------------------------
Thanks Jian He for your suggestion:-)
Overall summary to be in right direction. I am assuming that all scheduler
changes is only for CS. Is there any common scheduelr changes to be done ?
# Headroom will be dispalyed in application attempt page. This will be set as 0
once the attempt is finished.
# For each leaf queue in CS, UsedAMResource,UsedUserAMResource, 'User Limit for
User' will be displayed.
# In Active User, for each user link will be provided which redirect to
additional filtered user page containing userInfo in table as above sample
table. This is also applicable only for CS.
# All active users table wont be rendered. Instead only link will be provided
for each user i.e step-3 in active user. Am I understading is correct?
> Improve web UI to facilitate scheduling analysis and debugging

> Job may be stuck for reasons such as:
> - hitting queue capacity
> - hitting user-limit,
> - hitting AM-resource-percentage
> The first queueCapacity is already shown on the UI.
> We may surface things like:
> - what is user's current usage and user-limit;
> - what is the AM resource usage and limit;
> - what is the application's current HeadRoom;
