-----------------------------------
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.
