yew1eb opened a new issue, #1688: URL: https://github.com/apache/auron/issues/1688
**Describe the bug** using lpad(str, len, pad) or rpad(str, len, pad) with len as Int32 (Spark IntegerType) causes native execution to panic. Our lpad/rpad map to DataFusion implementations, whose signatures expect the second argument len to be Int64. The type mismatch leads to a cast failure and a runtime panic on the native side. <img width="709" height="593" alt="Image" src="https://github.com/user-attachments/assets/c2f57372-49e3-48af-84fa-1eb3d2742250"; /> **To Reproduce** Run: ``` CREATE TABLE pad_tbl(id INT, txt STRING, len INT, pad STRING) USING parquet; INSERT INTO pad_tbl VALUES(1, 'abc', 5, 'x'); SELECT LPAD(txt, len, pad), rpad(txt, len, pad) FROM pad_tbl; ``` Observed Error: ``` Caused by: java.lang.RuntimeException: java.lang.RuntimeException: poll record batch error: Execution error: native execution panics: Execution error: Execution error: output_with_sender[Project] error: Execution error: output_with_sender[Project]: output() returns error: Internal error: could not cast array of type Int32 to arrow_array::array::primitive_array::PrimitiveArray<arrow_array::types::Int64Type> ``` -- This is an automated message from the Apache Git Service.
