Hi all,
I have done the following steps to create a UDF in hive but getting error.Please help me.
1. Created the udf as described here.
2. Compiled it successfully.
3. Copy the class file to a directory hiveudfs.
4. Added it to a jar with this command: jar -cf hiveudfs.jar hiveudfs/SimpleUDFExample.class
5. Import the jar into hive. add jar hiveudfs.jar;  (Added Successfully)

create temporary function helloworld as 'hiveudfs.SimpleUDFExample';
At this I am getting the following error,
