An open-source storage framework that enables building a Lakehouse architecture with compute engines including Spark, PrestoDB, Flink, Trino, and Hive and APIs
Currently, we are using --target and --source to set the target JVM version, but it is known to cause issues when the jars are built using JDK17 to generate bytecode that is runnable using JVM 1.8 and above. See here for an example. Instead, use --release to generate the useable byte code in JVM 1.8 and above.
In contrast to the more widely known pair of—-source and—-target, the—-release switch will ensure that only byte code is produced that is actually usable with the specified Java version.
How was this patch tested?
Set JDK home to 17
./build/sbt clean publishM2
Edit kernel/examples/run-kernel-examples.py to comment the line clear_artifact_cache().
Set JAVA_HOME to 1.8
Run Kernel integration tests: ./kernel/examples/run-kernel-examples.py --version 3.2.1-SNAPSHOT
