[infinispan-issues] [JBoss JIRA] Created: (ISPN-658) DistributionManager not considerate of cache state changes

DistributionManager not considerate of cache state changes ---------------------------------------------------------- Key: ISPN-658 URL: https://jira.jboss.org/browse/ISPN-658 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 4.2.0.ALPHA2 Reporter: Paul Ferraro Assignee: Manik Surtani Considering a cache manager with 2 caches in DIST mode (C1 and C2) deployed on 2 nodes (N1 and N2). Currently, the DistributionManager does not properly handle the following scenarios: 1. Stop C1 on N1. This ought to trigger a rehash for the C1 cache. Currently, rehashing is only triggered via view change. Failure to rehash on stopping of a cache can inadvertently cause data loss, if all backups of a given cache entry have stopped. 2. A new DIST mode cache, C3, is started on N2. If N1 is the coordinator, the join request sent to N1 will get stuck in an infinite loop, since the cache manager on N1 does not contain a C3 cache. 3. Less critically, a new node, N3 is started. It does not yet have a C1 or C2 cache, though it's cache manager is started. This prematurely triggers a rehash of C1 and C2, even though there are no new caches instances to consider. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
