Aman Poonia created HBASE-30458:
-----------------------------------
Summary: 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
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.
