Ionut Ignatescu commented on HBASE-10309:
-----------------------------------------
[~jmhsieh]: Thank you for the respose, but it wasn't clear for me: if I delete
an empty region and I run hbck -repairHoles, what will be the effect?A new
empty region just as that was deleted or one of the neighboring regions will be
extended to cover the gap?
Thanks!
> Add support to delete empty regions in 0.94.x series

> Project: HBase
> Issue Type: New Feature
> Reporter: AcCud
>
> 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>
