Jieshan Bean created HBASE-9081:
-----------------------------------

             Summary: Online split for an reserved empty region with splits > 1
                 Key: HBASE-9081
                 URL: https://issues.apache.org/jira/browse/HBASE-9081
             Project: HBase
          Issue Type: New Feature
          Components: master, regionserver
            Reporter: Jieshan Bean


We already have a region splitter tool. But it can only provide limited functions:
1. Create table with a specified region number without give any splits.
2. Roll-Split on an exist region.

We have such user scenario: 
Table was created with splits like below: 
a____b____c____d____e____f____g____o
g~o is a reserved empty region. Will use it only after some days. So we don't know the rowkey
distribution currently. Will split it only when it get used.

Say, we want to split g~o with 10 new regions, likes g, g1, g2, g3, g4, g5.......,g9, o.

I didn't find similar function has already been there. Please tell me if I am wrong.
Hope to hear your ideas on this:)
