----------------------------------
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.
