facebook-hive-udfs's Introduction

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.

Alternatively, you can use the published jar included with this repo's packages.

You can add this repository as a maven source with:

<project>
...
  <repositories>
    <repository>
      <id>github</id>
      <name>facebook-hive-udfs</name>
      <url>https://maven.pkg.github.com/brndnmtthws/facebook-hive-udfs</url>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
    </repository>
  </repositories>
...
</project>

And then include it in your pom.xml:

<dependency>
  <groupId>com.airbnb</groupId>
  <artifactId>facebook-udfs</artifactId>
  <version>1.1.5</version>
</dependency>

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!!

udfarrayexclude doesn't work

First execute command on hive cli:
CREATE TEMPORARY FUNCTION udfarrayexclude AS 'com.facebook.hive.udf.UDFArrayExclude';
SELECT udfarrayexclude(array(1,2,3),array(1,2))

The result is as follows:
hive> SELECT udfarrayexclude(array(1,2,3),array(1,2));
OK
[1,2,3]
Time taken: 4.858 seconds, Fetched: 1 row(s)

why? In my opinion, the result should be [3]

Could someone give me some help?
