Summary: Be able to disable user limit factor for
CapacityScheduler Leaf Queue
Key: YARN-10531
URL: https://issues.apache.org/jira/browse/YARN-10531
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Wangda Tan
User limit factor is used to define max cap of how much resource can be
consumed by single user.
Under Auto Queue Creation context, it doesn't make much sense to set user limit
factor, because initially every queue will set weight to 1.0, we want user can
consume more resource if possible. It is hard to pre-determine how to set up
user limit factor. So it makes more sense to add a new value (like -1) to
indicate we will disable user limit factor
Logic need to be changed is below:
(Inside LeafQueue.java)
{code}
Resource maxUserLimit = Resources.none();
if (schedulingMode == SchedulingMode.RESPECT_PARTITION_EXCLUSIVITY) {
maxUserLimit = Resources.multiplyAndRoundDown(queueCapacity,
getUserLimitFactor());
} else if (schedulingMode == SchedulingMode.IGNORE_PARTITION_EXCLUSIVITY) {
maxUserLimit = partitionResource;
}
{code}
