[jira] Resolved: (HBASE-2697) Implement new open/close logic in
handlers and stop using heartbeats for open/close messages
[ https://issues.apache.org/jira/browse/HBASE-2697?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stack resolved HBASE-2697.
--------------------------

> This issue is doing the meat of what HBASE-2485 is about and continues what was started in HBASE-2694 after some code cleanup to make life easier.
> This deals with no longer piggybacking messages from Master to RegionServers on heartbeat responses and instead sending direct unsolicited messages. This also deals with moving the open/close logic fully into handlers and removing the existing open/close code on both the RS and M sides. There may also be some changes to the master in-memory state of regions in transition. The new load balancer will probably be introduced with this issue but not fully integrated yet.
