E-Learning: Writing UDFs for Pig

Pig is an Apache project that uses a scripting language to query and analyze large data sets. With Apache Pig, users can create MapReduce programs without writing Java code. This e-learning module teaches you how to write user-defined functions (UDFs) that can be executed inside of Pig to extend performance and develop a custom library of operations. We discuss what Pig UDFs are, supported functions and languages, and how to write custom UDFs in Java and Python. The module includes a hands-on exercise where you will write your own UDF in Python, complete with a sample solution.

E-Learning: Writing UDFs for Hive

Hive is an Apache project that facilitates ad hoc queries and analyses of large data sets in the Hadoop cluster using a SQL-like language. This e-learning module teaches you how to write user-defined functions (UDFs) to augment Hive's built-in capabilities. We discuss why UDFs are necessary, what kinds of UDFs exist, and how to write custom UDFs in Java. The module includes a hands-on exercise where you will write your own UDF, complete with a sample solution.

Video: Training a New Generation of Data Scientists

In this video, you will learn what data scientists do, how they think about problems, the relationship between data science and Hadoop, and how Cloudera‘s Introduction to Data Science course can help you join this growing and increasingly important profession, followed by Q&A with Cloudera Senior Director of Data Science Josh Wills.
