             Summary: The split parent region becomes online after cloning a snapshot
                 Key: HBASE-21084
                 URL: https://issues.apache.org/jira/browse/HBASE-21084
             Project: HBase
          Issue Type: Bug
            Reporter: Toshihiro Suzuki
            Assignee: Toshihiro Suzuki


Investigating HBASE-21015, I found another issue. It seems like after HBASE-20881, the split
parent region becomes online after cloning a snapshot.

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 date 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 becomes online.
