Bela Ban commented on JGRP-592:
-------------------------------
Implementing such a policy would be hard:
* The assumption that the first member of a view is the coordinator is a tenet of JGroups
as had been in place for a long time
* Therefore, there is a lot of code which depends on this. Locating that code and changing
it would be tedious
* Also, a lot of third party code depends on this as well
If we change this, the policy would therefore need to handle both the regular view change
and a merge view change, but in both cases, the coordinator needs to be the first of the
new view.
Pluggable policy for picking coordinator
----------------------------------------
Key: JGRP-592
URL:
https://issues.jboss.org/browse/JGRP-592
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Priority: Minor
Fix For: 3.4
Make policy to pick coordinator pluggable. Pick new coordinator after existing
coordinator crashes by calling this policy.
Default policy is to pick the next in line.
Other policies could pick the next in line from a set of pinned coordinator, so certain
members can never become coordinators.
