Facebook's Hive UDFs

WHAT IT IS

A computer guy at Facebook dumped a bunch of UDFs/UDAFs here:

https://issues.apache.org/jira/browse/HIVE-1545

However, the code does not build and is missing many parts.

This is a partial copy of that code, except it builds and may (or may not) work. Use at your own risk. To build it:

mvn package

This will produce a jar in target/ which you can add to your Hive classpath.

HOW DO USE IT?

Like any other UDF, silly!

Here's a sample:

CREATE TEMPORARY FUNCTION md5 AS 'com.facebook.hive.udf.UDFMD5';
SELECT md5(password) from users limit 1;

cool!!
