> For Express Upgrade,
> 1. We started the NameNodes with "-rollingUpgrade started" but were calling the wrong
finalize command, "-finalizeUpgrade" instead of "-rollingUpgrade finalize".
> 2. In HA, if safemode was already on, then the prepare step would fail since the grep
command reported an error.
> 3. In HA, we now check both NameNodes to come out of safemode. Before, this would only
run on the active one.
