maropu commented on issue #27024: [SPARK-29854]lpad and rpad built in function should throw Error or Exception for invalid length value URL: https://github.com/apache/spark/pull/27024#issuecomment-569399531 I just meant not the lpad behaivour but the type coercion behaivour; ``` hive> SELECT '1' + 1; 2.0 ``` If you want to fix this, I think we need to update the implicit cast logics instead of the lpad logic.
