                 Key: HBASE-5713
                 URL: https://issues.apache.org/jira/browse/HBASE-5713
             Project: HBase
          Issue Type: Bug
          Components: client, master, regionserver, shell
            Reporter: Subbu M Iyer
            Assignee: Subbu M Iyer
            Priority: Minor


There is a potential for region open/close stampede during instant schema change process as
the process attempts to close/open impacted regions in rapid succession. We need to introduce
some kind of throttling to eliminate the race condition.
