             Summary: Procedure V2 Phase 3: Notification Bus
                 Key: HBASE-14351
                 URL: https://issues.apache.org/jira/browse/HBASE-14351
             Project: HBase
          Issue Type: Task
            Reporter: Stephen Yuan Jiang
            Assignee: Matteo Bertozzi


This is the third phase of Procedure V2 (HBASE-12439) feature. Built on top of 
state­ machine from Phase 1 (HBASE-14336), the notification bus is just
an exchange of messages between the multiple machines (e.g. master and 
region­servers).  The notification ­bus allows master to send 
notifications/procedures to the Region Servers. Two examples are snapshot for 
OnePhaseProcedure and ACL update for TwoPhaseProcedure (check HBASE-12439 for 
high-level design).
