> Key: IGNITE-28255
> URL: https://issues.apache.org/jira/browse/IGNITE-28255
> Project: Ignite
> Issue Type: Bug
> Reporter: Alex Abashev
> Assignee: Alex Abashev
> Priority: Major
> Labels: IEP-132
> Fix For: 2.19
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h

> Summary:
> MarshallerCacheJobRunNodeRestartTest.testJobRun fails intermittently with
> timeout due to NotSerializableException in MarshallerMappingItem
> Description:
> The test MarshallerCacheJobRunNodeRestartTest.testJobRun hangs and times out
> after 5 minutes (300 000 ms).
> TC link:
> https://ci2.ignite.apache.org/test/381112157178694638?currentProjectId=IgniteTests24Java8&branch=%3Cdefault%3E
> Failure rate: 2 failures out of 68 runs (~3%), both on aitc-lin15, branch
> refs/heads/master (builds #41053, #41049)
> Root cause:
> During node restart, TcpDiscoverySpi fails to deserialize a discovery message
> because MarshallerMappingItem is not serializable:
> [ERROR][tcp-disco-sock-reader-...][TestTcpDiscoverySpi] Failed to read
> message
> org.apache.ignite.IgniteCheckedException: Failed to deserialize object with
> given class loader: IsolatedClassLoader\{roleName='test'}
> at
> org.apache.ignite.marshaller.jdk.JdkMarshallerImpl.unmarshal0(JdkMarshallerImpl.java:130)
> ...
> Caused by: java.io.WriteAbortedException: writing aborted;
> java.io.NotSerializableException:
> org.apache.ignite.internal.processors.marshaller.MarshallerMappingItem
> Caused by: java.io.NotSerializableException:
> org.apache.ignite.internal.processors.marshaller.MarshallerMappingItem
> MarshallerMappingItem is being sent as part of a TcpDiscovery message (likely
> a MarshallerMappingRequest or MarshallerMappingResponse) but does not
> implement Serializable. As a result, the restarting node cannot exchange
> marshaller mappings with the rest of the cluster, causing the worker thread
> to hang indefinitely waiting for the mapping to be resolved.
> This ultimately causes GridTestUtils.runMultiThreaded() to block forever at
> Thread.join(), triggering the 5-minute test timeout.
> Stack trace (thread dump at timeout):
> Thread
> [name="test-runner-#83435%cache.MarshallerCacheJobRunNodeRestartTest%",
> state=WAITING]
> at java.lang.Object.wait(Native Method)
> at java.lang.Thread.join(Thread.java:1304)
> at
> o.a.i.testframework.GridTestUtils.runMultiThreaded(GridTestUtils.java:1124)
> at
> o.a.i.i.processors.cache.MarshallerCacheJobRunNodeRestartTest.testJobRun(MarshallerCacheJobRunNodeRestartTest.java:65)
> Fix:
> MarshallerMappingItem should implement java.io.Serializable (or be converted
> to use Ignite's own serialization mechanism) so it can be properly
> marshalled/unmarshalled during TcpDiscovery message exchange.
> Environment:
> - Ignite version: 2.18.0-SNAPSHOT#20260317
> - JVM: OpenJDK 17.0.8.1+1 Eclipse Adoptium
> - OS: Linux 5.4.0-216-generic amd64
> - Agent: aitc-lin15
