Virtual nodes producing same hash id for two different cluster nodes -------------------------------------------------------------------- Key: ISPN-1275 URL: https://issues.jboss.org/browse/ISPN-1275 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 5.0.0.CR8 Reporter: Galder Zamarreño Assignee: Pete Muir Priority: Blocker Fix For: 5.0.0.FINAL Attachments: hashids.log While working on ISPN-1273, I've discovered that when virtual nodes are enabled, ConsistentHash.getHashIds(address) can return the same hash for two different cluster nodes. Example: with 500 virtual nodes, both NodeA-23181 and NodeB-39177 produce hash id *5289*.
