-----------------------------------
Assignee: Aman Poonia
> Allow selecting the JDK version in dev-support/hbase_docker build (--jdk
> 8|17|21)
> ---------------------------------------------------------------------------------
>
> Key: HBASE-30458
> URL: https://issues.apache.org/jira/browse/HBASE-30458
> Project: HBase
> Issue Type: Improvement
> Components: build
> Reporter: Aman Poonia
> Assignee: Aman Poonia
> Priority: Major
>
> The {{dev-support/hbase_docker/build-hbase.sh}} script builds HBase images
> that are hardcoded to Temurin JDK 8. That is no longer appropriate for
> master, which needs JDK 17 or later, and branch-2 should stay on JDK 8.
> h3. Changes
> * Add a {{--jdk <8|17|21>}} option to {{build-hbase.sh}} (also accepts
> {{--jdk=<v>}}, usable with --tag, --tarball and --source). Unsupported values
> fail fast with a clear error.
> * When {{--jdk}} is not given, use a per-branch default ({{DEFAULT_JDK}} in
> the script): 17 on master, 8 on branch-2.
> * {{Dockerfile}} and {{m1/Dockerfile}} take a {{JDK_VERSION}} build arg and
> select the matching Temurin tarball and SHA256. {{JAVA_HOME}} is set to
> {{/usr/lib/jvm/java-$\{JDK_VERSION\}}}. The JDK pins match
> {{dev-support/docker/Dockerfile}}.
> * Update {{dev-support/hbase_docker/README.md}}.
> h3. Testing
> * {{build-hbase.sh --source .}} on master (default JDK 17): build succeeds,
> image reports Temurin 17.0.11.
> * {{build-hbase.sh --source . --jdk 21}}: build succeeds, image reports
> Temurin 21.0.12.1.
> * JDK download and checksum stages verified for 8, 17 and 21; {{--jdk 11}} is
> rejected.
