This course offers a one-of-a-kind rich and interactive experience to learn the fundamentals and basics of Big Data. Throughout this course, you will have plenty of opportunities to get your hands dirty with functioning Hadoop clusters.

You will start off by learning about the rise of Big Data as well as the different types of data like structured, unstructured, and semi-structured data. You will then dive into the fundamentals of Big Data such as YARN (yet another resource manager), MapReduce, HDFS (Hadoop Distributed File System), and Spark.

By the end of this course, you will have the foundations in place to start working with Big Data, which is a massively growing field.

Introduction to Big Data and Hadoop

# Zookeeper in Practice

So far, we discussed the theory behind Zookeeper and saw a Java example with Zookeeper's programmatic API. In this lesson, we'll exercise different commands offered by the __zkCli.sh__ utility that come with the Zookeeper download. We fire up the Zookeeper server and then invoke the command line client to connect to the server. The various commands are listed in the widget below with an explanation for each. You can connect to the terminal below and execute the commands to see their outcome.

In this lesson we discuss the command line tool zkCli.sh that can be used to connect and interact with the Zookeeper server.
