Rohith commented on YARN-3284:

Thanks [~xgong] for working this jira.. [~leftnoteasy] for review..
Since patch size is huge, I think this task can be logically divide into 3 sub 
tasks which would help for reviewer for granular review and for implementer to 
rebase the code.
# API changes includes proto's
# Web UI  includes updating metrics
# Application CLI 
Any thoughts ? 

> Expose more ApplicationMetrics and ApplicationAttemptMetrics through YARN 
> command
