Error when creating custom UDFs
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,

Did you add the jar containing the class com.example.hive.udf.Lower using
"ADD JAR"? This error definitely occurs when the appropriate jar is not on
the path, and when there is a typo in class name. There are probably other
causes as well.

Seems that every time I execute :
create temporary function my_lower as 'com.example.hive.udf.Lower';
One lime with this error is added to the log file, my last lines are :
2010-05-17 14:55:28,500 ERROR ql.Driver (SessionState.java:printError(279))

Can you send the contents of /tmp/<username>/hive.log file? That should show a stack dump for this error.
