> Before sidelining a big overlap region, hbck tries to close it and offline it at first.
 However, sometimes, it throws NotServingRegion or UnknownRegionException.
> It could be because the region is not open/assigned at all, or some other issue.
> We should figure out why and fix it.
> By the way, it's better to print out in the log the command line to bulk load back sidelined
regions, if any.
