ASF GitHub Bot updated FLINK-39640:
-----------------------------------
Labels: pull-request-available (was: )
> Bump Flink 1.20.0 to 1.20.3 and upgrade maven-shade-plugin to 3.6.0
> -------------------------------------------------------------------
>
> Key: FLINK-39640
> URL: https://issues.apache.org/jira/browse/FLINK-39640
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Hive
> Affects Versions: 3.0.0
> Reporter: Jayesh Lalwani
> Priority: Major
> Labels: pull-request-available
>
> The Flink Hive connector CI is broken because flink-1.20.0-bin-scala_2.12.tgz
> has been removed from Apache's download mirrors (Apache only hosts the latest
> patch release per minor version). This prevents CI from running end-to-end
> tests.
> Bumping to Flink 1.20.3 fixes the binary download but introduces a transitive
> dependency change: flink-parquet:1.20.3 pulls in parquet-hadoop:1.15.2 (up
> from 1.13.1 in 1.20.0). The parquet 1.15.x line includes multi-release JAR
> entries with Java 17 and Java 22 class files under META-INF/versions/. The
> current maven-shade-plugin:3.2.4 (inherited from flink-connector-parent)
> cannot process these entries, failing with:
> {code}
> Unsupported class file major version 61
> {code}
> Fix:
> 1. Bump flink.version from 1.20.0 to 1.20.3
> 2. Override maven-shade-plugin version to 3.6.0 (supports multi-release JARs)
> 3. Update CI workflow to download flink-1.20.3 binary
