[jira] [Created] (SPARK-43218) Support "ESCAPE BY" in SparkScriptTransformationExec

jiang13021 created SPARK-43218:
----------------------------------

             Summary: Support "ESCAPE BY" in SparkScriptTransformationExec
                 Key: SPARK-43218
                 URL: https://issues.apache.org/jira/browse/SPARK-43218
             Project: Spark
          Issue Type: Wish
          Components: SQL
    Affects Versions: 3.4.0, 3.3.0, 3.2.0
            Reporter: jiang13021


If I don't `set spark.sql.catalogImplementation=hive`, I can't use "SELECT TRANSFORM" with "ESCAPE BY". Although HiveScriptTransform also doesn't implement ESCAPE BY, I can use RowFormatSerde to achieve this ability.

 

In fact, HiveScriptTransform doesn't need to connect to Hive Metastore. I can use reflection to forcibly call HiveScriptTransformationExec without connecting to Hive Metastore, and it can work properly. Maybe HiveScriptTransform can be more generic.
