Karthik Kambatla commented on YARN-5031:
----------------------------------------
By container reservation, do you mean the holds the scheduler places on nodes
to avoid starvation of large container requests? If yes, I don't think that is
a good idea. Instead, can we fix any bugs identified with container
reservation?
