pan3793 opened a new pull request, #7633:
URL: https://github.com/apache/kyuubi/pull/7633
### Why are the changes needed?
Flink 1.17, 1.18 and 1.19 are EOL and were deprecated earlier (KYUUBI #7199,
KYUUBI #7285),
with their building support already removed. Kyuubi 1.13 drops the remaining
support, making
Flink 1.20 the minimum. Flink 2.0 is EOL, so it is marked deprecated.
### What changes are proposed?
- Remove the flink-1.17/flink-1.18/flink-1.19 Maven profiles and their
deprecation warning
- Drop Flink 1.17/1.18/1.19 from the CI matrix
- Clean up stale adaptation code that only existed for Flink < 1.20,
including the
FlinkResultSet reflection shim, the 4-arg DefaultContext.load branch, and
>= "1.17" test guards
- Deprecate Flink 2.0 at engine startup
- Update docs to record the removal and deprecation
### How was this patch tested?
Cross-version tested: engine compiled with Flink 1.20, run against a Flink
2.3.0 distribution;
FlinkOperationSuite and FlinkOperationSuiteOnYarn passed 12/12.
CI coverage: the flink-it matrix keeps Flink 1.20 (JDK 8) plus Flink
2.0/2.1/2.2/2.3
binary verification (JDK 17). Spotless and Scalastyle pass.
