> o.a.h.conf.Configuration#get method interpret variables in a property in *-site.xml but Configuration#iterator method doesn't.
> For example, when a property "user.name" is set to "hadoop" and another property "hadoop.tmp.dir" is set to "/tmp/${user.name}", Configuration#get interpret "hadoop.tmp.dir" as "/tmp/hadoop" but Configuration#iterator doesn't interpret.
> I think Configuration#iterator should interpret variables or if there are some reasons, it should be documented that Configuration#iterator doesn't interpret variables.
