The `CapacityScheduler` supports the following parameters to control the
preemption of application containers submitted to a queue:
{noformat}
and:
{noformat}
| `yarn.scheduler.capacity.<queue-path>.disable_preemption` | This
configuration can be set true, to selectively disable preemption of application
containers submitted to a given queue. This will take impact only when system
wide preemption is enabled by configuring
`yarn.resourcemanager.scheduler.monitor.enable` to *true* and
`yarn.resourcemanager.scheduler.monitor.policies` to
*ProportionalCapacityPreemptionPolicy*. Preemptability will be inherited from
the parent's hierarchy unless explicitly overridden by a queue. Default value
is false.

should maybe be:
{noformat}
| `yarn.scheduler.capacity.<queue-path>.disable_preemption` | This
configuration can be set true to selectively disable preemption of application
containers submitted to a given queue. This will take effect only when system
wide preemption is enabled by configuring
`yarn.resourcemanager.scheduler.monitor.enable` to *true* and
`yarn.resourcemanager.scheduler.monitor.policies` to
*ProportionalCapacityPreemptionPolicy*. A queue's ability to be preempted is
inherited from its parent unless explicitly overridden for that queue. The
default value is false.
