Error when creating custom UDFs

[Edmar Ferreira]

Hi,

I am traying to create a UDF as describe in this tutorial :

http://wiki.apache.org/hadoop/Hive/HivePlugins


But when I use this command :

create temporary function my_lower as 'com.example.hive.udf.Lower';

I see this error :


FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.FunctionTask

Thanks,
