Re: MirrorMaker 2.0 XDCR / KIP-382

Hey Jeremy, it looks like you've got a typo or copy-paste artifact in the
configuration there -- you've got DC1->DC2 listed twice, but not the
reverse. That would result in the behavior you are seeing, as DC1 actually
has nothing enabled. Assuming this is just a mistake in the email, your
approach is otherwise correct.
