[infinispan-issues] [JBoss JIRA] Assigned: (ISPN-634) Merging on distributed caches can lead rehash failure

Merging on distributed caches can lead rehash failure ----------------------------------------------------- Key: ISPN-634 URL: https://jira.jboss.org/browse/ISPN-634 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 4.1.0.Final, 4.2.0.ALPHA1 Reporter: Galder Zamarreño Assignee: Vladimir Blagojevic Fix For: 4.2.0.BETA1, 5.0.0.BETA1 In the case of a MergeView, a node might be required to rejoin, meaning that it needs to rehash its keys. This can happen if the node is not in the winning partition. In this cases, rehash might fail because after the initial DistributionManagerImpl.joinComplete, because joinComplete is still set to true.
