> ----------------------------------------------------------------------------------------
>
> Key: HBASE-21053
> URL: https://issues.apache.org/jira/browse/HBASE-21053
> Project: HBase
> Issue Type: Bug
> Reporter: Toshihiro Suzuki
> Assignee: Toshihiro Suzuki
> Priority: Major
>
> 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}
> hbase> scan 'hbase:meta', \{FILTER => "PrefixFilter('test')"}
