Try changing ArrayList to just List as the argument to the evaluate function.

Help with simple UDF error..

[Manish]

Hello:
While running the hive query :

hive> select "Actor", count (*) from metrics where 
array_contains(type_tuple, "Actor") and checkAttributes 
(attribute_tuple, "p1", "Actor") ;


I get this error :

FAILED: SemanticException [Error 10014]: Line 1:103 Wrong arguments 
'"Actor"': No matching method for class yk.HiveCheckAllAttributes with 
(array, string, string). Possible choices: _FUNC_(string, 
string, string)



the metrics hive table schema looks like :

hive> describe metrics;
OK
col_name data_type comment
entity_uuid string
type_tuple array
attribute_tuple array


the class yk.HiveCheckAllAttributes extends UDF and has evaluate method 
defined as :


—snip--
public boolean evaluate(ArrayList payload, String pType, String 
type) {

…
}

I have tried Text type and still go the same error..
—snip--
public boolean evaluate(Text payload, String pType, String type) {
…
}



How can I pass Hive Array as an argument to a simple UDF?
