Is it possible to ask YARN to allocate one full physical machine (with all of its cores) to one application? E.g. If I need 24 cores and there is a machine in the cluster which has 24 cores, I would like to get that full physical box instead of 24 vcores which are potentially scattered in the cluster. Or if I have apriori knowledge that in my cluster no machine has less than n cores, I would like YARN to give me x machines (with all its cores) instead of asking in terms of vcores. ... View more
