Simple Hive UDF example

By |January 3rd, 2014|

Today I explored how to write your own custom UDF  in HIVE. There are two ways to create your UDF, one is  simple and the other is complex. The simple one allows you to create UDF with primitive Hadoop datatypes such as  Text, IntWritable, LongWritable, DoubleWritable, etc. extending UDF class.  For richer data types Map, List, Set you need to use the complex one extending GenericUDF class.
