> 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.
