Hello Christoph,
We are also facing same issue. We are working on HANA SPS 10 and trying to connect Hadoop using spark controller.
We are able to connect to Hadoop system. But after creating virtual table, we are unable to see the content. we are getting the below error.
Could not execute 'SELECT TOP 1000 * FROM "HDPUSER"."spark_demo_products"' SAP DBTech JDBC: [403]: internal error: Error opening the cursor for the remote database for query "SELECT "spark_demo_products"."productid",
Could you please help us on this issue.
Thank you.
Best regards,
Ram
