描述

Often when our customers try to deploy, Pinot returns Schema is incompatible with tableConfig with no details about the root-cause. We should try to return the exact reason why the Schema validation had failed.

研究方向
The issue is to improve error messages in SchemaUtils.java when schema validation fails. Locate the validation method at line 170-181 and modify it to capture the specific reason for failure (e.g., why the schema is incompatible with tableConfig). Consider using exceptions or validation result objects to propagate the reason. Check if there are any existing tests for this validation to understand expected behavior. The fix is localized and should not require cross module changes.
