> 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
> {code}
> create "test", "cf"
> {code}
> 2. Put some data into the table
> {code}
> (0...2000).each{|i| put "test", "row#{i}", "cf:col", "val"}
> {code}
> 3. Split the table
> {code}
> split "test"
> {code}
> 4. Take a snapshot of the table before CatalogJanitor cleans up the split parent region
> {code}
> snapshot "test", "snap"
> {code}
> 5. Clone the snapshot
> {code}
> clone_snapshot "snap", "cloned_table"
> {code}
> After following the above steps, the split parent region of the cloned table will be online.
