I figured it out. A jar is missing. ./src/build/contrib/hive-contrib-0.7.1.jar
If you don't see this jar, you need to go into src and run `ant` to build the extra jars. Then, you can do: DROP TABLE serde_regex; add jar ./src/build/contrib/hive-contrib-0.7.1.jar; create the table, load the data, and then you can do select on column. Adriaan
