In a Spark SQL environment, you are tasked with sharing a SQL UDF (User-Defined Function) across multiple users while ensuring security and ease of access. The solution must comply with organizational policies that restrict direct file sharing and require centralized access control. Considering these constraints, which of the following options best describes the security model for sharing SQL UDFs? Choose the best option.
A
Distribute the JAR file containing the UDF implementation directly to all users, bypassing centralized controls for simplicity.
B
Create a shared library in a central location accessible by all users, enabling them to access the UDF without individual file distribution.
C
Grant each user explicit file system permissions to the UDF's location, ensuring they can access it directly.
D
Register the UDF in a central registry accessible by all users, providing a standardized method for UDF sharing.
E
Both B and D are correct, offering secure and centralized methods for UDF sharing.
