Actually turns out I was confused. The dispatch doesn't work the way I thought. I've updated the v3 patch. Thanks for catching this.

> The NameNode can skip logging StandbyException messages. These are seen regularly in normal operation and convey no useful information.
> We no longer log the locations of newly allocated blocks in 2.8.0. The DN IDs can be useful for debugging so let's add that back.
