> 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}
