[jboss-jira] [JBoss JIRA] (JGRP-2303) RELAY2: notification when a site is up/down on all cluster nodes

[Bela Ban (Jira)]

    [ https://issues.jboss.org/browse/JGRP-2303?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13769033#comment-13769033 ] 

Bela Ban commented on JGRP-2303:
--------------------------------

The Relayer now notifies RELAY2 when a site comes up or goes down. RELAY2 in turn sends a local _non-relayed_ broadcast {{SITES_UP}}/{{SITES_DOWN}} (when it is the first of the site master(s)). On reception of that message, each member notifies its listeners.

> Provide a callback that's invoked on *all nodes* when a site is up/down, and possibly an initial view of the sites. Could be something like a 'sites view', e.g. \{"LON", "SFO"\}, \{"LON"\}, \{"LON", "SFO", "NYC\} etc
