Craig Welch commented on YARN-3318:
-----------------------------------
BTW, can't just do lexical sort on the string version of application id - one
problem with using the lexical compare on appid, the format for the "id"
component is a min of 4 digits, which means that going from 9999 to 10000 will
result in incorrect lexical sort wrt to actual order
> Create Initial OrderingPolicy Framework, integrate with CapacityScheduler
> LeafQueue supporting present behavior
