This Pig Tutorial will explain what is UDF in Pig. UDF is basically user-defined functions. You will learn these through a demo on Cloudera. A User Defined Function is something you write that pig loads and uses besides the existing built-in functions. Pig is a part of the Hadoop ecosystem that edited compositions a percentage of the lower level Hadoop functions using a useful scripting dialect called Pig Latin. This video will plunge into what happens when you find the need to amplify Pig Latin's base functionality through User Defined Functions (UDFs). For the most part, Pig has some built-in functions. We can utilize that Built-in function for our Pig Script without including any additional code, however now and again user prerequisite is not accessible in that built-in function, then the user can compose some own custom user-defined functions called UDF.
