Bela Ban commented on JGRP-592:
-------------------------------
Actually, I take the above statement back :-)
We can leave the basic tenet in place: the first element of the membership is always the
coordinator ! We only make the way the *membership is computed* pluggable. This needs to
be done in 2 places:
* When the coordinator determines the new membership
* When the coordinator is suspected and the next-in-line participant needs to determine
whether it will become the new coordinator
We also need to make the computation of the new MergeView in Merger.MergeTask.run()
pluggable
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.
