    mvn install -DskipTests -Dtar -Dhadoop.version=2.8.3

    The following figure shows that the compilation is successful.

    After the compilation is complete, the directory flink-1.9.1 is generated in flink-release-1.9.1/flink-dist/target/flink-1.9.1-bin/.

  8. Use the Kunpeng Porting Advisor to scan the .tar package generated after the compilation and ensure that the .tar package does not contain the x86 .so or .jar packages.
    • The compiled Flink package must be scanned by using the Kunpeng Porting Advisor to ensure that no x86 .so or .jar packages are contained. If the compiled package contains x86 .so or .jar packages, the component functions may be affected.
    • For details about how to use the Kunpeng Porting Advisor, see Kunpeng Porting Advisor Case Study.
