Class not found

[Mayuran Yogarajah]

I have a table with:
ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'
When I do a select on the table with a WHERE clause it runs a mapred job
which fails with the following:

java.lang.ClassNotFoundException: 
org.apache.hadoop.hive.contrib.serde2.RegexSerDe


I have copied $hive_build_dir/build/serde/hive_serde.jar into 
$hadoop_dir/lib.  I'm not
sure if I need to do anything else to get this working.  Can anyone help?

thanks
