It's ok for me to upgrade the JDK support to 17, which is more secure and stable, according to the survey(https://newrelic.com/resources/report/2024-state-of-the-java-ecosystem) JDK 17 is the most popular version in the Java ecosystem. Nevertheless, there are still some matters that we need to address.
- If you are using the `Hadoop` catalog, you need to ensure that the Hadoop version is compatible with JDK 17. Some older versions of Hadoop may not work properly with JDK 17. - Upgrading the JDK to 17 means that any users who are using the Gravitino server currently need to upgrade their JDK to 17 as well. I'm afraid that some users may not be able to upgrade their JDK to 17 due to compatibility issues with their applications or the environment. Anyway, the issues mentioned above don't prevent upgrading the JDK to 17, and I had the same idea long ago.
