Description

Investigating HBASE-21015, I found another issue. It seems like after HBASE-20881, the split parent region of the cloned table will be online when cloning a snapshot including a split parent region.

Steps to reproduce are as follows, which is the same as the steps in HBASE-21015:

1. Create a table

create "test", "cf"

2. Put some data into the table

(0...2000).each{|i| put "test", "row#{i}", "cf:col", "val"}

3. Split the table

split "test"

4. Take a snapshot of the table before CatalogJanitor cleans up the split parent region

snapshot "test", "snap"

5. Clone the snapshot

clone_snapshot "snap", "cloned_table"

After following the above steps, the split parent region of the cloned table will be online.
