> The ResourceManager strikes a balance between cluster utilization and strict enforcement
of resource invariants in the cluster. Individual allocations of containers must be reclaimed-
or reserved- to restore the global invariants when cluster load shifts. In some cases, the
ApplicationMaster can respond to fluctuations in resource availability without losing the
work already completed by that task (MAPREDUCE-4584). Supplying it with this information would
be helpful for overall cluster utilization [1]. To this end, we want to establish a protocol
for the RM to ask the AM to release containers.
