Description

Flink version 1.16.2 has compatibility issues with certain production environments and dependencies. Downgrading to Flink 1.12.2 provides better stability and compatibility with existing deployments.

Steps to reproduce

N/A - This is a version compatibility fix

Expected behavior

The project should build and run successfully with Flink 1.12.2, maintaining compatibility with production Hadoop environments and dependent libraries.

Your environment

  • Linkis version used: 2.0.0
  • Environment name and version:
    • hadoop 3.3.4
    • flink 1.16.2 → 1.12.2
    • jdk 1.8.0_xxx

Anything else

This change downgrades the flink.version property in the root pom.xml from 1.16.2 to 1.12.2 to resolve compatibility issues with the production environment.
