> The description of property {{dfs.namenode.stale.datanode.interva}} in 
> hdfs-default.xml doesn't mention about the time unit, we should add that to 
> avoid confusing users.
> I have reviewed all properties in hdfs-default.xml, this is the only one 
> property causes such confusion, user should be able to easily figure out the 
> appropriate time unit for properties by either
> * Specified by property name, e.g 
> dfs.namenode.full.block.report.lease.length.ms
> * Specified by property value with time unit suffix, e.g 
> dfs.blockreport.initialDelay=0s
> * Explained by description of the property, e.g 
> dfs.namenode.safemode.extension=3000, description: Determines extension of 
> safe mode in milliseconds ...
> change to the property name and value will be an incompatible change, to 
> minimize the impact, propose to simply add the time unit in the description 
> (3rd approach). And this should be only one property needs the fix in 
> hdfs-default.xml.
