[infinispan-issues] [JBoss JIRA] Commented: (ISPN-902) Data consistency across rehashing

Data consistency across rehashing --------------------------------- Key: ISPN-902 URL: https://issues.jboss.org/browse/ISPN-902 Project: Infinispan Issue Type: Bug Reporter: Erik Salter Assignee: Manik Surtani Priority: Critical Attachments: cacheTest.zip There are two scenarios we're seeing on rehashing, both of which are critical. 1. On a node leaving a running cluster, we're seeing an inordinate amount of timeout errors, such as the one below. The end result of this is that the cluster ends up losing data. org.infinispan.util.concurrent.TimeoutException: Timed out waiting for valid responses! at org.infinispan.remoting.transport.jgroups.JGroupsTransport.invokeRemotely(JGroupsTransport.java:417) at org.infinispan.remoting.rpc.RpcManagerImpl.invokeRemotely(RpcManagerImpl.java:101) at org.infinispan.distribution.DistributionManagerImpl.retrieveFromRemoteSource(DistributionManagerImpl.java:341) at org.infinispan.interceptors.DistributionInterceptor.realRemoteGet(DistributionInterceptor.java:143) at org.infinispan.interceptors.DistributionInterceptor.remoteGetAndStoreInL1(DistributionInterceptor.java:131) 06:07:44,097 WARN [GMS] cms-node-20192: merge leader did not get data from all partition coordinators [cms-node-20192, mydht1-18445], merge is cancelled at org.infinispan.commands.read.GetKeyValueCommand.acceptVisitor(GetKeyValueCommand.java:59) 2. Joining a node into a running cluster causes transactional failures on the other nodes. Most of the time, depending on the load, a node can take upwards of 8 minutes to join. I've attached a unit test that can reproduce these issues.
