stack commented on HBASE-9864: ------------------------------ bq .... not being worked on. ... in time for 1.0 release (to my knowledge -- correct me if I am wrong) > Notifications bus for use by cluster members keeping up-to-date on changes > -------------------------------------------------------------------------- > > Key: HBASE-9864 > URL: https://issues.apache.org/jira/browse/HBASE-9864 > Project: HBase > Issue Type: Brainstorming > Reporter: stack > Priority: Blocker > > In namespaces and acls, zk callbacks are used so all participating servers > are notified when there is a change in acls/namespaces list. > The new visibility tags feature coming in copies the same model of using zk > with listeners for the features' particular notifications. > Three systems each w/ their own implementation of the notifications all using > zk w/ their own feature-specific watchers. > Should probably unify. > Do we have to go via zk? Seems like all want to be notified when an hbase > table is updated. Could we tell servers directly rather than go via zk? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
