> ContainerLocalizer or ResourceLocalizationService will use the ReadWriteDiskValidator
as its disk validator when it downloads files if we configure the yarn.nodemanger.disk-validator
to ReadWriteDiskValidator's name. In that case, ReadWriteDiskValidator will create a metric
item for each directory localized, which will be too many metrics. We should let ContainerLocalizer
only use the basic disk validator.
