Review comment:
> In this case, the user is looking at the meta table specifically.
Maybe the below `if (metaLocation != null) {...` needs an `else` block that
prints a message stating that some region location(s) could not be identified?
Since the user may learn the meta region is in transition state from the
transition list in Master status UI， Should we still show any details here?
After I check the current implementation it shows that If a region of
user-level table is in transition, it does not be displayed in its table
details page. So I think the meta region should be the same.
