Examples of UDF

org.apache.ambari.view.pig.resources.udf.models.UDF
Bean to represent User Defined Functions
org.apache.hadoop.hive.ql.exec.UDF
A User-defined function (UDF) for the use with Hive. New UDF classes need to inherit from this UDF class. Required for all UDF classes: 1. Implement one or more methods named "evaluate" which will be called by Hive. The following are some examples: public int evaluate(); public int evaluate(int a); public double evaluate(int a, double b); public String evaluate(String a, int b, String c); "evaluate" should never be a void method. However it can return "null" if needed.
