Wilfred Spiegelenburg commented on YUNIKORN-2107:
-------------------------------------------------
We used to have this until it was removed in 1.3.0 as part of the [partition
config|https://yunikorn.apache.org/docs/next/user_guide/queue_config#partitions]:
{code:java}
* preemption (deprecated since v1.3.0){code}
Reinstating that parameter is less intrusive and makes more sense than adding a
new entry in the config map. Turn off preemption as part of the queue
configuration is where I think it belongs. That same object could be used to
set a different global default for the preemptionDelay instead of the 30s
> Allow preemption to be disabled globally

> Currently, there is no way to disable preemption on a global basis. As
> preemption still has some know issues, it would be useful to allow a global
> flag to disable it.

> We should add a configmap entry "service.disablePreemption" (defaulting to
> false) that can be used to disable the preemption logic entirely.
