Eric Payne commented on YARN-7370:
----------------------------------
Thanks [~leftnoteasy], [~sunilg], and [~GergelyNovak].
So, just to be clear, I think we would all like the following preemption
properties to be refreshable with {{yarn rmadmin -refreshQueues}}:
{noformat}
yarn.resourcemanager.scheduler.monitor.enable
yarn.resourcemanager.monitor.capacity.preemption.max_ignored_over_capacity
yarn.resourcemanager.monitor.capacity.preemption.max_wait_before_kill
yarn.resourcemanager.monitor.capacity.preemption.monitoring_interval
yarn.resourcemanager.monitor.capacity.preemption.natural_termination_factor
yarn.resourcemanager.monitor.capacity.preemption.observe_only
yarn.resourcemanager.monitor.capacity.preemption.select_based_on_reserved_containers
yarn.resourcemanager.monitor.capacity.preemption.total_preemption_per_round
yarn.scheduler.capacity.lazy-preemption-enabled
# Intra-queue-specific properties:
yarn.resourcemanager.monitor.capacity.preemption.intra-queue-preemption.enabled
yarn.resourcemanager.monitor.capacity.preemption.intra-queue-preemption.minimum-threshold
yarn.resourcemanager.monitor.capacity.preemption.intra-queue-preemption.max-allowable-limit
yarn.resourcemanager.monitor.capacity.preemption.intra-queue-preemption.preemption-order-policy
{noformat}
I do NOT think we want to refresh
{{yarn.resourcemanager.scheduler.monitor.policies}} since that would require
stopping and restarting the monitor thread. At least, if we want to make this
refreshable, I suggest that we do it as part of a separate JIRA.
Also, just FYI, the
{{yarn.scheduler.capacity.root.\[QUEUEPATH\].disable_preemption}} property is
already refreshable.
