Based on the provided information, it seems like the issue is related to the caching mechanism of the view refresh functionality in the Apache Hudi project. The files you've provided are:

  1. TestHoodieTableFileSystemView.java - This is a test file for the HoodieTableFileSystemView class in the Apache Hudi project. This class is responsible for providing a view of the file system for a Hudi table. The issue might be related to how this class handles caching and refreshing the view.

  2. Hoodie_OSS.json - This is a JSON configuration file for a Grafana dashboard. Grafana is a tool for visualizing time series data. The issue might be related to how the dashboard is configured to refresh its view and how it interacts with the caching mechanism.

Here are the actions that should be taken:

  1. Review the HoodieTableFileSystemView class: Start by understanding how this class works, especially how it handles caching and refreshing the view. Look for any methods that are related to these functionalities.

  2. Review the test file TestHoodieTableFileSystemView.java: Understand what the tests are doing, especially any tests that are related to the view refresh functionality. If there are no such tests, it might be a good idea to write some.

  3. Review the Hoodie_OSS.json file: Understand how the Grafana dashboard is configured, especially any settings related to refreshing the view. Look for the "refresh" and "refresh_on_load" settings in the JSON file.

  4. Reproduce the issue: If possible, try to reproduce the issue in a controlled environment. This will help you understand exactly what's going wrong.

  5. Debug the issue: Use debugging tools to step through the code and understand where it's failing. This will help you pinpoint the exact location of the issue.

  6. Fix the issue: Once you've located the issue, you can start working on a fix. This might involve changing how the HoodieTableFileSystemView class handles caching and refreshing, or it might involve changing the Grafana dashboard settings.

  7. Test the fix: After implementing the fix, make sure to test it thoroughly to ensure that it actually solves the issue and doesn't introduce any new ones.

  8. Document the fix: Finally, document what the issue was and how you fixed it. This will be helpful for anyone who encounters the same issue in the future.
