----------------------------------------
Summary: A state of a replica region of a split parent region is
wrong after splitting the region
Key: HBASE-21053
URL: https://issues.apache.org/jira/browse/HBASE-21053
Project: HBase
Issue Type: Bug
Reporter: Toshihiro Suzuki
Assignee: Toshihiro Suzuki
Steps to reproduce are as follows:
1. Create a table with region replication
{code}
create "test", "cf", \{REGION_REPLICATION => 2}
{code}
2. Load data to the table
{code}
(0...2000).each\{|i| put "test", "row#{i}", "cf:col", "val"}
{code}
3. Split the table
{code}
split "test"
{code}
After that, the state of the replica region of the split parent region
(info:state_0001) is CLOSING, but the correct state is CLOSED.
{code}
