sandflee commented on YARN-5082:
--------------------------------
Thanks [~asuresh],
1, priority was defined in FSAppAttempt as app priority, if using "Priority
priority = request.getPriority()", it will generate check style warning like
'priority' hides a field. change the name of priority seems make it more clear,
thought?
2, yes, the container maybe not created yet and will be null.
3, will do
> ContainerId rapidly increased in fair scheduler if the num of node app
> reserved reached the limit
