Summary: Affinity may be not calculated properly in case of merged exchanges with client nodes Key: IGNITE-7987 URL: https://issues.apache.org/jira/browse/IGNITE-7987 Project: Ignite Issue Type: Bug Components: cache Affects Versions: 2.4 Reporter: Pavel Kovalenko Assignee: Pavel Kovalenko Fix For: 2.5 Currently we pass only last (or first in some cases) discovery event for affinity calculation at GridAffinityAssignmentCache. Affinity calculation can be skipped if such discovery event belongs to client node or node filtered by nodeFilter for optimization issues (because affinity will not be changed in such case). Since we have exchange merging there can be several discovery events corresponds to one exchange. Passing only first or last event for affinity calculation is wrong, because calculation can be skipped, while exchange actually contains events changing affinity. Instead of first/last event we should pass whole collection of discovery events (ExchangeDiscoveryEvents) and skip affinity calculation for a group only when ALL events doesn't change affinity for such group. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
