>
> Currently, SLS uses unmanaged AM for simulated map-reduce applications. And first allocated
container for each app is considered to be the master container.
> This could be problematic when preemption happens. CapacityScheduler preempt AM container
at lowest priority, but the simulated AM container isn't recognized by scheduler -- it is
a normal container from scheduler's perspective.
> This JIRA tries to fix this logic: do the real AM allocation instead of using unmanaged
AM.
