Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The job is using an outdated version of the table schema.
AWS Glue jobs can cache the table schema at job start. If the table schema is updated while the job is running, the job may still reference the old schema version, which may no longer exist in the Data Catalog, causing a 'Resource Not Found' error even though the table exists. Option B is incorrect because concurrent writes do not cause this specific error; they may cause conflicts but not a 'Resource Not Found' for the table itself. Option C is incorrect because if the table exists and the location is wrong, it would typically result in a different error (e.g., 'Access Denied' or 'PathNotFound') rather than 'Resource Not Found' for the table. Option D is incorrect because special characters in the job name do not affect table access.
