--------------------------------------
Assuming from the stacktrace, it seems like the plugin's issue. I am
tentatively resolving this.
> SAP HANA : Truncate doesn't truncate the table but rather drops the table
> -------------------------------------------------------------------------
>
> Key: SPARK-37245
> URL: https://issues.apache.org/jira/browse/SPARK-37245
> Project: Spark
> Issue Type: Bug
> Components: PySpark
> Affects Versions: 3.1.0
> Reporter: Balaji Balasubramaniam
> Priority: Major
>
> Hello,
> I currently use AWS Glue 3.0 version. Python version is 3 and the Spark
> version is 3.1 and I'm using the latest SAP HANA JDBC driver (ngdbc.jar). I
> can able to use this jar to read the data from SAP HANA but when I'm trying
> to write the data to SAP HANA, I notice that it is trying to drop the table,
> rather than truncating the table. Upon talking to AWS support, they mentioned
> that HANA JDBC dialect is not support, thus it is not honoring the truncate
> option, is this true?
> This is the option that I use:
> df_lake.write.format("jdbc").option("url", edw_jdbc_url).option("driver",
> "com.sap.db.jdbc.Driver").option("dbtable", edw_jdbc_db_table).option("user",
> edw_jdbc_userid).option("password", edw_jdbc_password).option("truncate",
> "true").mode("append").save()
> This is the stack trace:
