SAP HANA Vora 1.2 : Cannot load as virtual table in HANA Studio

Question

In SAP HANA Vora 1.2 Dev Edition: I've configured the Spark Controller and started server. Then I run the spark-shell and created a new table. In SAP HANA Studio i can see now folder "spark_velocity" and "table001" in it, which I created. When I try to add this table my HANA folder with "Add as Virtual Table" option I receive an error:

SAP DBTech JDBC: [476]: invalid remote object name: Unable to retrieve remote metadata for SparkSQL.spark_velocity.SparkSQL.spark_velocity.table001: line 0 col 0 (at pos 0)

And here is full Exception:

com.sap.db.jdbc.exceptions.JDBCDriverException: SAP DBTech JDBC: [476]: invalid remote object name: Unable to retrieve remote metadata for SparkSQL.spark_velocity.SparkSQL.spark_velocity.table001: line 0 col 0 (at pos 0)

I have seen this issue when incompatible versions were used. With Vora 1.2 you need Spark Controller 1.5 Patch 5 (HANASPARKCTRL00P_5-70001262.RPM) and HANA SPS11. Also make sure to configure the Spark Controller with the Vora1.2 datasources jar (spark-sap-datasources-1.2.33-assembly.jar).
