Description

Steps to reproduce are as follows:

1. Create a table with region replication

create "test", "cf", \{REGION_REPLICATION => 2}

2. Load data to the table

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

3. Split the table

split "test"

After that, the state of the replica region of the split parent region (info:state_0001) is CLOSING, but the correct state is CLOSED.
