Review comment:
Changing this may break backward compatibility in the Datanode since the
value of this constant is written down to and read from the Version file. We
can either leave it as it is, or make sure that the writers always use
"layoutVersion", and the readers fall back to "layOutVersion" if the default is
not present.
