> I've found that the datanode container data scrubber defaults to have an scan 
> interval if 1minute:
> {code:java}
> // ContainerScrubberConfiguration.java
> @Config(key = "data.scan.interval",
>     type = ConfigType.TIME,
>     defaultValue = "1m", 
> ...{code}
> It is too short since data scan is a heavy read load which may make normal IO 
> slow,
> so a longer interval should be used as default, for example 1d.
