Multi-key write commands assume all segments have CH.getNumOwners() owners -------------------------------------------------------------------------- Key: ISPN-7998 URL: https://issues.jboss.org/browse/ISPN-7998 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.1.0.Beta1, 9.0.3.Final Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 9.1.0.Final When handling multi-key write commands, both {{TriangleDistributionInterceptor}} and {{NonTxDistributionInterceptor}} assume that there are no backup owners when {{consistentHash.getNumOwners() == 1}}. But during rebalance some segments can have more than {{getNumOwners()}} owners, as the write CH is a union of the current and future CHs, while {{getNumOwners()}} always returns the value in the cache configuration.
