Passing Joins to Spark

For a multiple libref join to pass to Spark, all of these components of the LIBNAME statements must match exactly.

• user ID (USER=)
• password (PASSWORD=)
• server (SERVER=)
• port (PORT=)
• schema (SCHEMA=, where the URI= host or port should match if you specified URI=)

You can use the SQL pass-through facility to pass a cross-schema join to Spark. For more information, see Passing Joins to the DBMS.
