Capacity Scheduler Preemption Timeouts

[#1]

In the Fair Scheduler there are parameters for setting the algos that run preemption. This allows a window for containers to become available without killing them off. A standard is 300 seconds. I searched for a similar parameter in Capacity Scheduler using preemption but did not find it. Is there a back off period and if so what is that period? Is there a parameter to configure this window?

How about yarn.resourcemanager.monitor.capacity.preemption.max_wait_before_kill ? The default is 15 sec (15000 ms), see here and here for details.
