> There are multiple reasons why preemption could unnecessarily preempt containers. One
is that an app could be requesting a large container (say 8-GB), and the preemption monitor
could conceivably preempt multiple containers (say 8, 1-GB containers) in order to fill the
large container request. These smaller containers would then be rejected by the requesting
AM and potentially given right back to the preempted app.
