Hello Marco,
I am also facing same issue.
We are able to connect to Hadoop system. But after creating virtual table, we are not able to see any content in the table. 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",
Are you facing the same issue Marco?
Best regards,
Ram
