View Curriculum
  • You will need to have a background in IT. The course is aimed at Software Engineers, System Administrators, DBAs who want to learn about Big Data
  • Knowing any programming language will enhance your course experience
  • The course contains demos you can try out on your own machine. To run the Hadoop cluster on your own machine, you will need to run a virtual server. 8 GB or more RAM is recommended.

In this course you will learn Big Data using the Hadoop Ecosystem. Why Hadoop? It is one of the most sought after skills in the IT industry. The average salary in the US is $112,000 per year, up to an average of $160,000 in San Fransisco (source: Indeed).

The course is aimed at Software Engineers, Database Administrators, and System Administrators that want to learn about Big Data. Other IT professionals can also take this course, but might have to do some extra research to understand some of the concepts.

You will learn how to use the most popular software in the Big Data industry at moment, using batch processing as well as realtime processing. This course will give you enough background to be able to talk about real problems and solutions with experts in the industry. Updating your LinkedIn profile with these technologies will make recruiters want you to get interviews at the most prestigious companies in the world.

The course is very practical, with more than 6 hours of lectures. You want to try out everything yourself, adding multiple hours of learning. If you get stuck with the technology while trying, there is support available. I will answer your messages on the message boards and we have a Facebook group where you can post questions.

Who is the target audience?
  • This course is for anyone that wants to know how Big Data works, and what technologies are involved
  • The main focus is on the Hadoop ecosystem. We don't cover any technologies not on the Hortonworks Data Platform Stack
  • The course compares MapR, Cloudera, and Hortonworks, but we only use the Hortonworks Data Platform (HDP) in the demos

MapReduce WordCount, step by step explained

MapReduce WordCount Example

A demo of MapReduce WordCount on our HDP cluster

Demo: MapReduce WordCount

In HDFS, files are divided in blocks and stored on the DataNodes. In this lecture we're going to see what happens when we're reading lines from files that potentially span over multiple blocks.

Lines that span blocks

Introducing Yarn, and concepts like the ResourceManager, the scheduler, the applicationsManager, the NodeManager, and the Application Master. I explain how an application is executed and the consequences when a node crashes.

Introduction to Yarn

A demo of an application executed using yarn jar. I provide an overview of Ambari Yarn metrics and the ResourceManager UI

Demo: Yarn and ResourceManager UI

Ambari also exposes a REST API. Commands can be executed directly to this API. Ambari also lets you do unattended install using Ambari Blueprints

Ambari API and Blueprints

A demo showing you the Ambari API and how to work with blueprints

Demo: Ambari API and Blueprints

An introduction to ETL processing in Hadoop. MapReduce, Pig, and Spark are suitable to do batch processing. Hive is more suitable for data exploration.

Introduction to Pig

This demo shows how to install pig and tez using Ambari on the Hortonworks Data Platform

Demo: Part 1 - Pig Installation

In this demo I will show you basic pig commands to load, dump and store data. I'll also show you an example how to filter data.

Demo: Part 2 - Pig Commands

More Pig commands in this final part of the pig demo. I'll go over commands like GROUP BY, FOREACH ... GENERATE and COUNT()

Real Time Processing
1 Lecture 02:53

All the lectures up until now were batch oriented. From now on we're going to discuss Realtime processing technologies like Kafka, Storm, Spark Streaming, and HBase / Phoenix.

Introduction to Realtime Processing
5 Lectures 19:14

An introduction to Kafka and its terminology like Producers, Consumers, Topics and Partitions.

Introduction to Kafka

An explanation of Kafka Topics covering Leader partitions, Follower partitions, and how writes are sent to the partitions. Also covers the Consumer groups to show the difference between publish-subscribe (pubsub) mechanism and queuing

Kafka Topics

Kafka guarantees at-least-once message delivery, but can also be configured for at-most-once. Log Compaction is a technique that Kafka provides to have a full dataset maintained in the commit log. This lecture shows an example of a customer dataset fully kept in Kafka and explains Log Tail, Cleaner Point and Log Head and how it impacts consumers.

Kafka Messages and Log Compaction

A few example use cases of Kafka

Kafka Use Cases and Usage

  • At least once delivery
  • Exactly once delivery

This lecture also explains the Storm's reliability API (Anchoring and Acking) and the performance impact of acking.

Storm Message Processing and Reliability

An introduction to the Trident API, an alternative interface for Storm that supports exactly-once processing of messages.

Spark Streaming
7 Lectures 17:35

Spark streaming is an alternative to Storm that gained a lot of popularity in the last few years. It allows you to reuse the code you wrote in batch and use it for stream processing.

Introduction to Spark Streaming

Spark Streaming generates DStreams, micro-batches of RDDs. This lecture explains the Spark Streaming Architecture

Spark Streaming Architecture

This lecture explains possible receivers, like Kafka. It also shows a WordCount streaming example, where data is ingested from Kafka and processed using WordCount in Spark Streaming

Spark Receivers and WordCount Streaming Example

This demo shows the Kafka-spark-streaming example.

Demo: Spark Streaming with Kafka

In the previous lecture we did a WordCount using Spark Streaming, but our example was stateless. In this lecture I'm adding state, using UpdateStateByKey to keep state and checkpointing to save the data to HDFS.

Spark Streaming State and Checkpointing

A demo of a stateful spark streaming application. Performs a global WordCount from a topic from Kafka. Does checkpointing in HDFS.

DevOps, Cloud, Big Data Specialist

I've been a System Administrator and full stack developer for over 10 years, the typical profile for a DevOps engineer. I've been working in multiple organizations and startups. I've cofounded a startup that focusses on applying DevOps and Cloud. I have been training people in newer technologies, like Big Data. I've trained a lot of people working in FTSE 100 & S&P 100 companies. Today I mainly work together with companies to improve their software delivery processes, while coaching and teaching on platforms like Udemy.
