[jboss-jira] [JBoss JIRA] Commented: (JGRP-1061) FLUSH: asymmetric merge fails

FLUSH: asymmetric merge fails ----------------------------- Key: JGRP-1061 URL: https://jira.jboss.org/jira/browse/JGRP-1061 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.8 A: {B,A,C} B: {B,C} C: {B,C} B and C have the same view, but A has a different (older) view which still includes B and C The new merge now determines that the partition coordinators for the merge are B and A. When FLUSH is enabled, before handling the merge request A tries to flush {A,B,C} and B tries to flush {B,C}. The latter works, but the former fails as A cannot communicate with B and C ! SOLUTION: the partition for A needs to be {A} and not {B,A,C}. Is this possible in all cases, or can we NOT prevent merging of overlapping partitions ? (Then flush would always fail !)
