                 Key: HIVE-17874
                 URL: https://issues.apache.org/jira/browse/HIVE-17874

When a parquet table contains an unsupported type like {{Map}}, {{LIST}} or {{UNION}} simple queries like {{select count(*) from table}} fails with {{unsupported type exception}} even though vectorized reader doesn't really need read the complex type into batches.
