I was reading this:
It sounded like I can pass some configuration or context to the UDF but I
can't figure out how I would do that after I searched quite a bit on
internet and past discussion.
In my UDF, I can also do this:
UDFContext context = UDFContext.getUDFContext();
Properties properties context.getUDFProperties(this.getClass());
so if the context is set on the front end, supposedly, it will be in that
properties object. But how do I set it on the front end or whichever way to
pass it to UDF?
