--------------------------------
Summary: Internal error on RETURNS TABLE
Key: SPARK-51289
URL: https://issues.apache.org/jira/browse/SPARK-51289
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 4.0.0
Reporter: Max Gekk
While testing the 4.0.0-rc1, I have found the internal error on the new feature:
{code:sql}
spark-sql (default)> CREATE TEMPORARY FUNCTION fa(x INT) RETURNS TABLE (a INT)
RETURN SELECT x;
Time taken: 0.325 seconds
spark-sql (default)> select * from fa(1);
{code}
{code:java}
[INTERNAL_ERROR] SQL table function plan should be rewritten during analysis:
SQLTableFunction fa,
SQLFunction(fa,Some(StructType(StructField(x,IntegerType,true))),Right(StructType(StructField(a,IntegerType,true))),None,Some(SELECT
x),None,Some(true),None,true,HashMap(referredTempFunctionsNames -> [],
catalogAndNamespace.part.0 -> spark_catalog, referredTempViewNames -> [],
catalogAndNamespace.part.1 -> default,
sqlConfig.spark.sql.artifact.isolation.enabled -> false,
catalogAndNamespace.numParts -> 2,
sqlConfig.spark.sql.datetime.java8API.enabled -> true,
referredTempVariableNames -> []),None,1740153099265), [1], [a#3]
SQLSTATE: XX000
{code}
