             Summary: Safely handle new closures of IGNITE-11392 in mixed cluster environment
                 Key: IGNITE-11735
                 URL: https://issues.apache.org/jira/browse/IGNITE-11735
             Project: Ignite
          Issue Type: Improvement
            Reporter: Ivan Rakov
            Assignee: Denis Chudov
             Fix For: 2.8


Under IGNITE-11392 we have added two new closures (FetchActiveTxOwnerTraceClosure and TxOwnerDumpRequestAllowedSettingClosure).
In case we'll assemble mixed cluster (some nodes contain the patch, some don't), we may bump into situation when closures are sent to node that doesn't contain corresponding classes in classpath. Normally, closurer will be deployed to "old" node via peer-to-peer class deployment. However, p2p may be disabled in configuration, which will cause ClassNotFoundException on "old" node.
We should register IGNITE-11392 in IgniteFeatures (recent example: IGNITE-11598) and filter out nodes that don't support new feature before sending compute.
