Answer

Hi,

Please ensure your table names, schemas, database names, and column names are all correct.

The “HIVE_INVALID_METADATA” happens when the AWS Glue table schema contains duplicate column names or columns with the same name as partition columns.
To resolve the error please follow the steps in the documentation here:

As for the “GENERIC_INTERNAL_ERROR” there could be several different things causing this. Please refer to the following documentation that describes the different error cases and steps to resolve:

https://aws.amazon.com/premiumsupport/knowledge-center/athena-generic-internal-error/

Hope this helps.
