Facebook's Hive UDFs
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.
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!!
