[infinispan-issues] [JBoss JIRA] Resolved: (ISPN-1077) Multiple leaves are not handled correctly with DIST

Multiple leaves are not handled correctly with DIST ---------------------------------------------------- Key: ISPN-1077 URL: https://issues.jboss.org/browse/ISPN-1077 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 4.2.1.FINAL Reporter: Mircea Markus Assignee: Dan Berindei Fix For: 5.0.0.CR4, 5.0.0.FINAL Attachments: MultipleNodesLeavingTest.java When multiple caches are leaving at the same time(i.e. the diff between jgroups views is more than one address), Infinispan ends up with an inconsistent hash function: it is aware about nodes that are no longer present in the cluster. The root cause of the problem is in DistributionManagerImpl.rehash(...): - the list of leavers is determined as follows: Address leaver = MembershipArithmetic.getMemberLeft(oldMembers, newMembers); - this method always assumes a single leaver, but there can be many. Unit test attached.
