The GitHub Actions job "Flink CDC CI" on flink-cdc.git/FLINK-40040 has failed. Run started by GitHub user Zhile (triggered by yuxiqian).
Head commit for run: 9465a73200154aaa017a3ba4aadc3e2f2a1bea62 / Jiyong Wang <[email protected]> [FLINK-40040][cdc-runtime] Wrap coordinator failure in SerializedThrowable across RPC boundary SchemaRegistry.failJob now wraps the failure cause into a SerializedThrowable before it crosses the operator-coordinator RPC boundary, and runInEventLoop routes through failJob so all exits share the wrapping. Otherwise an exception whose class only lives in the user classloader (e.g. the MySQL driver's com.mysql.cj.exceptions.ConnectionIsClosedException raised during table discovery) fails to deserialize on the receiving side, where flink-rpc-akka uses an isolated classloader, with ClassNotFoundException. The coordination response is then lost and the SchemaOperator request stalls until rpcTimeout, failing with a misleading TimeoutException and turning a transient error into a restart loop that only a full job restart recovers from.
