Arun Suresh commented on YARN-5082:
-----------------------------------
Nice catch [~sandflee], In general, i think the patch looks ok. Minor nits:
# Any reason you changed the name of the priority variable ?
# I am guessing you changed the argument of isReservable from 'container' to
'capability' since you have delayed creating the container until the reserve
method.. can you confirm ?
# Maybe good to have a test case to verify that new containers are not
generated.
> ContainerId rapidly increased in fair scheduler if the num of node app
> reserved reached the limit
