Students: 167147, Price: Free

The objective of this course is to walk you through step by step of all the core components in Hadoop but more importantly make Hadoop learning experience easy and fun.

By enrolling in this course you can also get free access to our multi-node Hadoop training cluster so you can try out what you learn right away in a real multi-node distributed environment.

ABOUT INSTRUCTOR(S)

We are a group of Hadoop consultants who are passionate about Hadoop and Big Data technologies. 4 years ago when we were looking for Big Data consultants to work in our own projects we did not find qualified candidates because the big data industry was very new and hence we set out to train qualified candidates in Big Data ourselves giving them a deep and real world insights in to Hadoop.

WHAT YOU WILL LEARN IN THIS COURSE

In the first section you will learn about what is big data with examples. We will discuss the factors to consider when considering whether a problem is big data problem or not. We will talk about the challenges with existing technologies when it comes to big data computation. We will breakdown the Big Data problem in terms of storage and computation and understand how Hadoop approaches the problem and provide a solution to the problem.

In the HDFS, section you will learn about the need for another file system like HDFS. We will compare HDFS with traditional file systems and its benefits. We will also work with HDFS and discuss the architecture of HDFS.

In the MapReduce section you will learn about the basics of MapReduce and phases involved in MapReduce. We will go over each phase in detail and understand what happens in each phase. Then we will write a MapReduce program in Java to calculate the maximum closing price for stock symbols from a stock dataset.

In the next two sections, we will introduce you to Apache Pig & Hive. We will try to calculate the maximum closing price for stock symbols from a stock dataset using Pig and Hive.

Spark Starter Kit

NOT another "What is Spark?" course ! Explore Spark in depth and get a strong foundation in Spark.

Students: 51350, Price: Free

When our students asked us to create a course on Spark, we looked at other Spark related courses in the market and also what are some of the common questions students are asking in websites like stackoverflow and other forums when they try to learn Spark and we saw a recurring theme.

Most courses and other online help including Spark's documentation is not good in helping students understand the foundational concepts. They explain what is Spark, what is RDD, what is "this" and what is "that" but students were most interested in understanding core fundamentals and more importantly answer questions like - 

  1. Why do we need Spark when we have Hadoop ? 
  2. What is the need for RDD ?
  3. How Spark is faster than Hadoop?
  4. How Spark achieves the speed and efficiency it claims ?
  5. How does memory gets managed in Spark?
  6. How fault tolerance work in Spark ?

and that is exactly what you will learn in this free Spark Starter Kit course. The aim of this course is to give you a strong foundation in Spark.
