(Glue-2105) Q: I'm getting the error message "Java processing failed at RFC destination '…'". However, when I test the RFC connection through transaction SM59, it seems to be working fine. What is the problem?

Datavard Glue uses RFC calls to connect to external databases such as Hadoop. However, the RFC call from SAP is translated into other protocols (e.g. JDBC) through a Java connector. When you test the RFC connection to this Java connection, it will show the status of the connection between the SAP Netweaver ABAP stack and the Java connector. However, the connection between the Java connector and the external database (e.g. HIVE) may be down. To find out where the root cause of the problem is, a RFC connection check is not sufficient. Please check the protocols of the Java connector, using program /DVD/SM_HIVE_DISPLAY_JAVA_LOG.
