> In r1182034 per-Store metrics were broken, because the aggregation of
> StoreFile metrics over all stores in a region was replaced by overriding them
> every time. We saw these metrics drop by a factor of numRegions on a
> production cluster -- thanks to Kannan for noticing this! We need to fix the
> metrics and add a unit test to ensure regressions like this don't happen in
> the future.
