An Apache Hadoop Hive GenericUDF wrapper around the uap-clj library providing Browser, O/S, and Device field extraction functions.
##Setup for development (optional)
###Running the test suite
This project uses speclj. The core test suite comprises almost entirely test generators built from reading in test fixtures from the ua-parser/uap-core repository, which themselves are pulled into the local workspace as dependencies using tobyhede/lein-git-deps.

Created /Users/<username>/dev/uap-clj-hiveudf/target/uap-clj-hiveudf-1.3.1-standalone.jarCopy one or both of these artifacts to a preferred location in HDFS (e.g. hdfs:///shared/jars).
The standalone version is huge; the other version tiny. The latter is preferred assuming you have
all the prerequisite dependencies (specified in project.clj) in your classpath. In the example below,
we'll be assuming the standalone version for the purposes of initially trying out the UDF while
minimizing setup hassle.
###Java and Hive version dependencies
This code has been tested using the hive commandline client versions v0.12.0, v0.14.0, and v1.0.0, and the beeline HiveServer2 client used in the examples here. The deployed hadoop artifact itself compiles and runs under either Java v1.7 or v1.8 (tested with OpenJDK).

0: jdbc:hive2://example.com:> describe function device;
+---------------------------------------------------------+--+

+---------------------------------------------------------+--+
| Takes a useragent & returns struct<family,brand,model> |
+---------------------------------------------------------+--+
1 row selected (0.728 seconds)If you don't already have a source of useragent data in form of SELECTable columns of useragent strings in an existing Hive table, you can populate an external table by copying a text file comprising user agent strings, one per line, to a location in HDFS:
0: jdbc:hive2://example.com:> CREATE EXTERNAL TABLE raw_useragent(agent STRING)
. . . . . . . . . . . . . . > ROW FORMAT DELIMITED
. . . . . . . . . . . . . . > LINES TERMINATED BY '\n'
. . . . . . . . . . . . . . > STORED AS TEXTFILE
. . . . . . . . . . . . . . > LOCATION '/shared/data/raw/useragent';
No rows affected (0.755 seconds)Note that we've left off a FIELDS TERMINATED BY specification, since each line corresponds to one field. This is the simplest case of a Hive table, EXTERNAL or regular:
0: jdbc:hive2://example.com:> describe raw_useragent;
+-----------+------------+----------+--+
| col_name | data_type | comment |
+-----------+------------+----------+--+
| agent | string | |
+-----------+------------+----------+--+
1 row selected (1.534 seconds)Assuming you've moved a source text file (or several) to hdfs:///shared/data/raw/useragent, you should see a populated external table the size of the number of lines in your source file:
0: jdbc:hive2://example.com:> select count(*) as rowcount from raw_useragent;

1 row selected (19.59 seconds)Now you're ready to play with your data and try out your UDFs:
: jdbc:hive2://example.com:> SELECT agent,
. . . . . . . . . . . . . .> browser(agent) AS browser,
. . . . . . . . . . . . . .> os(agent) AS os,
