voonhous opened a new issue, #19957: URL: https://github.com/apache/hudi/issues/19957
The Trino connector fails merge-on-read real-time queries on Trino 484 and later: ``` java.lang.SecurityException: Forbidden org.apache.hudi.avro.model.HoodieWriteStat! This class is not trusted to be included in Avro schemas. ``` Trino bumped Avro from 1.12.1 to 1.12.2 in trinodb/trino@8aafdce48d1, and the hudi-trino plugin bundles that version. Avro 1.12.2 added `ClassSecurityValidator`, which `ClassUtils.forName` runs on every class loaded by name. By default it trusts only a few JDK classes. `HoodieAvroUtils.convertToSpecificRecord` resolves nested records through `SpecificData.getClass(schema)`, which goes through that check, so Hudi's own generated classes are rejected. Affected reads: - commit metadata with write stats, which the connector reads to resolve the table schema - log files with delete blocks (`HoodieDeleteRecordList`) Hudi itself builds on Avro 1.11.4 and released Trino 483 bundles 1.12.1, so neither has hit this yet. The Trino E2E suite on #19953 showed it once it ran on the pinned Trino ([run](https://github.com/apache/hudi/actions/runs/34940577669/job/104288110394)). Workaround until a fix ships: start every Trino node with `-Dorg.apache.avro.SERIALIZABLE_PACKAGES=org.apache.hudi.avro.model`. -- This is an automated message from the Apache Git Service.
