> Capacity preemption is enabled as follows.
>  *  yarn.resourcemanager.scheduler.monitor.enable= true ,
>  *  yarn.resourcemanager.scheduler.monitor.policies=org.apache.hadoop.yarn.server.resourcemanager.monitor.capacity.ProportionalCapacityPreemptionPolicy
> Queue = a,b
> Capacity of Queue A = 80%
> Capacity of Queue B = 20%
> Step 1: Assign a big jobA on queue a which uses full cluster capacity
> Step 2: Submitted a jobB to queue b  which would use less than 20% of cluster capacity
> JobA task which uses queue b capcity is been preempted and killed.
> This caused below problem:
> 1. New Container has got allocated for jobA in Queue A as per node update from an NM.
> 2. This container has been preempted immediately as per preemption.
> Here ACQUIRED at KILLED Invalid State exception came when the next AM heartbeat reached
RM.
> ERROR org.apache.hadoop.yarn.server.resourcemanager.rmcontainer.RMContainerImpl: Can't
handle this event at current state
> org.apache.hadoop.yarn.state.InvalidStateTransitonException: Invalid event: ACQUIRED
at KILLED
> This also caused the Task to go for a timeout for 30minutes as this Container was already
killed by preemption.
