I think their init script has special handling for "upgrade" as an argument. There's no way they're passing it though, since it's hitting hadoop-daemon.sh... We can verify, but I think that's something they've handled in their non-generic init scripts.
The bundled init scripts do not pass any arguments to the underlying services, which is needed for things like upgrading the namenode metadata. See Step 5 here: http://www.cloudera.com/content/www/en-us/documentation/enterprise/latest/topics/cdh_ig_earlier_cdh5_upgrade.html.
I believe these are just options that get passed through. (and need to check HDP as well).
