Cancelled segment transfer causes future entry transfer to be ignored --------------------------------------------------------------------- Key: ISPN-4154 URL: https://issues.jboss.org/browse/ISPN-4154 Project: Infinispan Issue Type: Bug Security Level: Public(Everyone can see) Components: State Transfer Affects Versions: 7.0.0.Alpha1 Reporter: Radim Vansa Assignee: Dan Berindei Priority: Critical Distributed transactional cache. 1) Coordinator is gracefully leaving the cluster, sends a REBALANCE_START with topologyId 14, ST begins. 2) Node receives chunk from segment X, writes entry K=V to the container. 3) New coordinator jumps in with CH_UPDATE topology 16 4) Node receives CANCEL_STATE_TRANSFER and cancels transfer of segment X, invalidating K. In CommitManager, this operation is tracked and DiscardPolicy is set to DISCARD_STATE_TRANSFER for key K. 5) New coordinator starts rebalance with topology 17 6) Node starts new ST for segment X 7) Node receives the X: K=V, but in CommitManager it finds out that the policy is set to DISCARD_STATE_TRANSFER and ignores this update. Result: entry value is lost on some node.
