Pradeep Ambati commented on YARN-8680:
--------------------------------------

Thanks for the review [~jlowe].

I have addressed all but one issues you pointed out. I didn't address this 
comment.

{quote}It would be cleaner to have a LocalResourceTrackerState constructor that 
takes the values as arguments and then mark the internal 
LocalResourceTrackerState fields as final. Then there is no need to have setter 
methods for LocalResourceTrackerState.{quote}

This is a bit complex, as LocalTrackerState is present in 
RecoveredLocalizationState and RecoveredUserResources and the way these class 
objects are initialized the LocalTrackerState of respective class object is 
assigned/initialized later than they are created/intialized. I will look into a 
way to do this and if possible put a patch for that.
