The world of Hadoop and "Big Data" can be intimidating - hundreds of different technologies with cryptic names form the Hadoop ecosystem. With this Hadoop tutorial, you'll not only understand what those systems are and how they fit together - but you'll go hands-on and learn how to use them to solve real business problems!

Learn and master the most popular big data technologies in this comprehensive course, taught by a former engineer and senior manager from Amazon and IMDb. We'll go way beyond Hadoop itself, and dive into all sorts of distributed systems you may need to integrate with.

  • Install and work with a real Hadoop installation right on your desktop with Hortonworks (now part of Cloudera) and the Ambari UI

  • Manage big data on a cluster with HDFS and MapReduce

  • Write programs to analyze data on Hadoop with Pig and Spark

  • Store and query your data with Sqoop, Hive, MySQL, HBase, Cassandra, MongoDB, Drill, Phoenix, and Presto

  • Design real-world systems using the Hadoop ecosystem

  • Learn how your cluster is managed with YARN, Mesos, Zookeeper, Oozie, Zeppelin, and Hue

  • Handle streaming data in real time with Kafka, Flume, Spark Streaming, Flink, and Storm

Understanding Hadoop is a highly valuable skill for anyone working at companies with large amounts of data.

Almost every large company you might want to work at uses Hadoop in some way, including Amazon, Ebay, Facebook, Google, LinkedIn, IBM,  Spotify, Twitter, and Yahoo! And it's not just technology companies that need Hadoop; even the New York Times uses Hadoop for processing images.

This course is comprehensive, covering over 25 different technologies in over 14 hours of video lectures. It's filled with hands-on activities and exercises, so you get some real experience in using Hadoop - it's not just theory.

You'll find a range of activities in this course for people at every level. If you're a project manager who just wants to learn the buzzwords, there are web UI's for many of the activities in the course that require no programming knowledge. If you're comfortable with command lines, we'll show you how to work with them too. And if you're a programmer, I'll challenge you with writing real scripts on a Hadoop system using Scala, Pig Latin, and Python.

You'll walk away from this course with a real, deep understanding of Hadoop and its associated distributed systems, and you can apply Hadoop to real-world problems. Plus a valuable completion certificate is waiting for you at the end! 

Please note the focus on this course is on application development, not Hadoop administration. Although you will pick up some administration skills along the way.

Knowing how to wrangle "big data" is an incredibly valuable skill for today's top tech employers. Don't be left behind - enroll now!

Big data is a combination of structured, semi structured and unstructured data collected by organizations that can be mined for information and used in machine learning projects, predictive modelling and other advanced analytics applications.

Systems that process and store big data have become a common component of data management architectures in organizations, combined with tools that support big data analytics uses. Big data is often characterized by the three V's:

  • the large volume of data in many environments;

  • the wide variety of data types frequently stored in big data systems; and

  • the velocity at which much of the data is generated, collected and processed.

Big data is a great quantity of diverse information that arrives in increasing volumes and with ever-higher velocity.

Big data can be structured (often numeric, easily formatted and stored) or unstructured (more free-form, less quantifiable).

Nearly every department in a company can utilize findings from big data analysis but handling its clutter and noise can pose problems.

Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins.

Big data is most often stored in computer databases and is analysed using software specifically designed to handle large, complex data sets.

Topics Covered in these course are:

  • Big Data Enabling Technologies

  • Hadoop Stack for Big Data

  • Hadoop Distributed File System (HDFS)

  • Hadoop MapReduce

  • MapReduce Examples

  • Spark

  • Parallel Programming with Spark

  • Spark Built-in Libraries

  • Data Placement Strategies

  • Data Placement Strategies

  • Design of Zookeeper

  • CQL (Cassandra Query Language)

  • Design of HBase

  • Spark Streaming and Sliding Window Analytics

  • Kafka

  • Big Data Machine Learning

  • Machine Learning Algorithm K-means using Map Reduce for Big Data Analytics

  • Parallel K-means using Map Reduce on Big Data Cluster Analysis

  • Decision Trees for Big Data Analytics

  • Big Data Predictive Analytics

  • PageRank Algorithm in Big Data

  • Spark GraphX & Graph Analytics

  • Case Studies of big companies and how they operate.

Taught by a team which includes 2 Stanford-educated, ex-Googlers  and 2 ex-Flipkart Lead Analysts. This team has decades of practical experience in working with large-scale data processing. 

Has your data gotten huge, unwieldy and hard to manage with a traditional database? Is your data unstructured with an expanding list of attributes? Do you want to ensure your data is always available even with server crashes? Look beyond Hadoop - the Cassandra distributed database is the solution to your problems.

Let's parse that.

  • Huge, unwieldy data: This course helps your set up a cluster with multiple nodes to distribute data across machines
  • Unstructured: Cassandra is a columnar store. There are no empty cells or space wasted when you store data with variable and expanding attributes
  • Always available: Cassandra uses partitioning and replication to ensure that your data is available even when nodes in a cluster go down


What's included in this course:

  •  The Cassandra Cluster Manager (CCM) to set up and manage your cluster
  •  The Cassandra Query Language (CQL) to create keyspaces, column families, perform CRUD operations on column families and other administrative tasks
  • Designing primary keys and secondary indexes, partitioning and clustering keys
  • Restrictions on queries based on primary and secondary key design
  • Tunable consistency using quorum and local quorum. Read and write consistency in a node
  • Architecture and Storage components: Commit Log, MemTable, SSTables, Bloom Filters, Index File, Summary File and Data File

Updated for Spark 3.0

In this course, we will learn how to stream big data with Apache Spark 3. You'll write 1500+ lines of Spark code yourself, with guidance, and you will become a rockstar.

This course is for Spark & Scala programmers who now need to work with streaming data, or who need to process data in real time.

Why Spark in Scala:

  • it's blazing fast for big data

  • its demand has exploded

  • it's a highly marketable skill

  • it's well maintained, with dozens of high-quality extensions

  • it's a foundation for a data scientist

I like to get to the point and get things done. This course 

  1. deconstructs all concepts into the critical pieces you need

  2. selects the most important ideas and separates them into what's simple but critical and what's powerful

  3. sequences ideas in a way that "clicks" and makes sense throughout the process of learning

  4. applies everything in live code

The end benefits are still much greater:

  • a completely new mental model around data streaming

  • significantly more marketable resume

  • more enjoyable work - Spark is fun!

This course is for established programmers with experience with both Scala and Spark at least at the level of the Rock the JVM essential courses for Scala and Spark. I already assume a solid understanding of general programming fundamentals.

This course is NOT for you if

  • you've never written Scala or Spark code before

  • you don't have some essential parallel programming background (e.g. what's a process/a thread)

The course is comprehensive, but you'll always see me get straight to the point. So make sure you have a good level of focus and commitment to become a badass programmer.

I believe both theory and practice are important. That's why you'll get lectures with code examples, real life code demos and assignments, plus additional resources, instructions, exercises and solutions. At the end of the course, you'll have written thousands of lines of Spark.

I've seen that my students are most successful - and my best students work at Google-class companies - when they're guided, but not being told what to do. I have exercises waiting for you, where I offer my (opinionated) guidance but otherwise freedom to experiment and improve upon your code.

Definitely not least, my students are most successful when they have fun along the way!

Web accessibility is often something that gets pushed to the side. It’s easy to assume that all users can see, user a keyboard, use a mouse or touch screen, and overall interact with your website or product content the same way you do. But this simply isn’t true. Assuming everyone can use things in the exact same ways leads to an experience that works well for some people, but creates major issues or barriers for others.

Accessibility is starting to gain more traction in the design and tech industries, especially since more and more countries are creating laws surrounding accessibility. If you’re a web designer or a UI/UX designer of any level who doesn’t feel confident in their accessibility knowledge, this is the course that’ll level you up with practical skills.

What you’ll learn in this course:

  • How to design for those with vision impairment of different degrees

  • How to design for those with color vision impairment

  • How to design for those who are hearing impaired

  • Keyboard accessibility for all users

  • Creating target areas that work for all users

  • What accessibility tools are available to you

TWO high-quality practice tests with 60 questions each must help you become a certified Apache Cassandra Administrator Associate, passing DataStax Academy's proctored certification exam:

  • Each practice test has 60 questions, for 90 minutes, with a 70% passing score - just like the real exam.

  • Domains mapped to areas from the recommended courses: Architecture, Operations, Data Modeling, CQL.

  • Includes several questions from my other Become a Certified Cassandra Developer: Practice Exams.

  • All questions are original, with detailed explanations and references.

  • Questions closely emulate those from the actual exam, without duplicating them.

  • Same level of difficulty as the latest exam questions, changed in mid-2020.

  • Unlike the real exam, you'll know right away what questions you missed, and what the correct answers are.

  • Detailed explanations with external references for any possible choice, in all practice test questions.

  • Just like the actual exam, questions are all single-select, with four possible choices to select from.

  • DataStax can provide vouchers to try and retry their exam for FREE, after watching some of their videos.

  • Otherwise, the list price for the real exam has been cut down to $145 US.

How should I use these tests?

  1. Try first practice test. And do not worry about the time or if you fail. You are expected to fail, this is how you learn...

  2. Stop the exam anytime, if you're not patient enough to go over all 60 questions.

  3. Once done, you get your total score, plus per domain. These are the same domains used in the actual exam.

  4. Click Review Questions and scroll down to both the right and wrong choices for each individual question (remember these!).

  5. Read the detailed Explanation for each question. This is something else you don't have at the actual exam...

  6. Repeat with the second practice test. Don't skip it, as both these tests together cover most types of actual exam questions.

  7. Repeat these tests again and again, until you score at least 90% on each. And then go for the real deal. Good luck!

Everyone has the potential to understand and work with energy! This course is a practical guide to help you understand and optimize your energy flow.

This information comes from the New Healing Connection® Course I created based on over 15 years of experience working with patients with chronic pain and other disorders. My goal is to empower you to heal yourself and change your life.

I start by explaining my understanding of energy flow and how energy imbalances develop. I talk about what healthy energy flow feels like and how to recognize if you have an energy imbalance.

Then I delve deeper into the idea of energy healing and what energy healers do. I explain ideas like auras and chakras. I also share how you can use your understanding of energy to make a link between your life stressors and physical health.

We also cover information on energy expenditures. You'll learn how to be aware of your energy expenditures on your activities and relationships and how to start spending your energy more wisely.

You’ll discover how energy debts affect you, including how energy debts lead to physical illness and chronic pain.

Finally you'll learn how to apply all that you’ve learned about energy to change your unhealthy habits and make a shift in your health and your life.

Remember, you have more power than you can imagine—power to heal yourself and change your life—starting from the inside out!

Creating An Effortless Life

From the author of "Living The I Am"

When I first read about the law of least effort, it appeared in Deepak Chopra’s book, Seven Spiritual Laws of Success. It read, “Nature’s intelligence functions with effortless ease, with carefreeness, harmony, and love. And when we harness the forces of harmony, joy, and love, we create success and good fortune with effortless ease.” Seeing myself as a scientist, I decided to practice this law deliberately. Those who know me well—know that I am a task-driven methodological person who thrives in the concept of “getting it done.” I believe in the concept of “the process” and have had nightmares of losing my book of standard operating procedures on the basics of life.

I reached that point in my life where I began to question all this hard work. And it felt like the harder I worked, the more I became stressed and unfilled. I constantly felt like I was in a rat race going nowhere fast. I did not want to be one of those people who work hard for 50 years, only to retire waiting on a monthly check from social security, rocking in my chair, and not having the strength to do anything else.

This course and workbook are the beginning of your awakening. Within these pages, you'll find gems that you can use immediately to transform the way you show up in life. The next seven days will inspire you to move through the concepts understanding that in order to transform anything you must first be willing to release.
