Amithsha updated YARN-9662:
---------------------------
Description:
Preemption on node labels is not working when the utilization is 100%.
Example
adhocp0,adhocp1,adhocp3 Queues mapped to nodelabels of label_adhoc_nm.
With a share of 60,30,10 as actual capacity and 100 as maximum capacity for
all.
When a jobA on adhocp3 consumes 100% of its maximum capacity and a jobB
submitted on adhocp0 no containers running on adhocp3 queue got preempted.
This is already reported by another user
https://issues.apache.org/jira/browse/YARN-7685
Note :
Jobs with more than actual capacity and less than the maximum capacity are able
to preempt the containers.
