I'm running into the same issue, and I see that it's addressed in HIVE-2223.
In the meantime, I'm getting an error when trying to use the reflect() function
:
SELECT reflect("org.apache.commons.lang.StringUtils", "join", collectedSet), ...
FAILED: Error in semantic analysis: Line 1:69 Argument type mismatch
collectedSet: The parameters of
GenericUDFReflect(class,method[,arg1[,arg2]...]) must be primitive (int,
double, string, etc).
