stack commented on HBASE-10309:
-------------------------------

Removing a single empty region is not possible without region merge facility.  If multiple adjacent empty regions, you could replace them all with a single empty region that spans the deleted regions easy enough.

> My use case: I have several tables where keys start with a timestamp. Because of this and combined with the fact that I have set a 15 days retention period, after a period of time results empty regions.
> I am sure that no write will occur in these region.
> It would be nice to have a tool to delete regions without being necessary to stop the cluster.
> The easiest way for me is to have a tool that is able to delete all empty regions, but there wouldn't be any problem to specify which region to delete.
> Something like:
> deleteRegion <tableName> <region>
