Jonathan Hsieh commented on HBASE-10309:
----------------------------------------
My main concern is doing this safely and in a simple way -- hbck repairs stuff
is mostly for after problems occur when we are already messed up. Purposely
"breaking" things and then using hbck is just risky. We could outline steps on
how to do this but it requires some expertise in case something bad happens.
> Add support to delete empty regions in 0.94.x series

> Key: HBASE-10309
> URL: https://issues.apache.org/jira/browse/HBASE-10309
> Project: HBase
> Issue Type: New Feature
> Reporter: AcCud
> Fix For: 0.94.17
>
>
> 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>
