A `<version>` here would override what's in the `spark-parent` POM. So this
would force it to `hadoop.version`. `yarn.version` itself defaults to take the
value of `hadoop.version`, but is separate so that they could be set separately
back in the days when the versions didn't track each other. A system property
would override values set in the POM's profiles.
