>
> During region split/merge there's a brief period of time where doing a "Get"
> with "closest_row_before=true" on "hbase:meta" may return empty
> "GetResponse.result.cell" field even though parent, splitA and splitB regions
> are all in "hbase:meta". Both gohbase (https://github.com/tsuna/gohbase) and
> AsyncHBase (https://github.com/OpenTSDB/asynchbase) interprets this as
> "TableDoesNotExist", which is returned to the client.
> Here's a gist that reproduces this problem:
> https://gist.github.com/Timoha/c7a236b768be9220e85e53e1ca53bf96. Note that
> you have to use older HTable client (I used 1.2.4) as current versions ignore
> `Get.setClosestRowBefore(bool)` option.
