@Hoang LeCapacity Scheduler’s leaf queues can also use the user-limit-factor
property to control user resource allocations. This property denotes the fraction of queue capacity that any single user can consume up to a maximum value, regardless of whether or not there are idle resources in the cluster.
Property: yarn.scheduler.capacity.root.support.user-limit-factor
Value: 1
The default value of "1" means that any single user in the queue can at maximum only occupy the queue’s configured capacity. This prevents users in a single queue from monopolizing resources across all queues in a cluster. Setting the value to "2" would restrict the queue's users to twice the queue’s configured capacity. Setting it to a value of 0.5 would restrict any user from using resources beyond half of the queue capacity.
These settings can also be dynamically changed at run-time using yarn rmadmin - refreshQueues
.
Please change user limit factor and try.
