Description

On Mozilla cluster, hbck reported empty info:regioninfo but then also that there were regions in fs that were not deployed. At least one of these regions w/ an empty info:regioninfo matches to the region in fs that is not in the .META. hbck should be able to pick up the region from ms and fix the .META. entry on --fix.
