[infinispan-issues] [JBoss JIRA] (ISPN-6308) Stream iterator method can fail sometimes with a node failure

Stream iterator method can fail sometimes with a node failure ------------------------------------------------------------- Key: ISPN-6308 URL: https://issues.jboss.org/browse/ISPN-6308 Project: Infinispan Issue Type: Bug Components: Distributed Execution and Map/Reduce Affects Versions: 8.1.2.Final Reporter: William Burns Assignee: William Burns Fix For: 8.2.0.Final While adding some additional changes for replication using distributed streams I ran the stress test. I found that iterator could fail somehow. Need to patch this issue.
