> I found incomplete queue info shown on scheduler page and NPE in RM log when rendering
the info table of leaf queue in non-accessible partitions.
> {noformat}
> Caused by: java.lang.NullPointerException

> The direct cause is that PartitionQueueCapacitiesInfo of leaf queues in non-accessible
partitions are incomplete(part of fields are null such as configuredMinResource/configuredMaxResource/effectiveMinResource/effectiveMaxResource)
but some places in CapacitySchedulerPage don't consider that.
