Course description

  • What’s the focus of this course?

    The Big Data Hadoop and Spark developer course have been designed to impart an in-depth knowledge of Big Data processing using Hadoop and Spark. The course is packed with real-life projects and case studies to be executed in the CloudLab.

    Mastering Hadoop and related tools: The course provides you with an in-depth understanding of the Hadoop framework including HDFS, YARN, and MapReduce. You will learn to use Pig, Hive, and Impala to process and analyze large datasets stored in the HDFS, and use Sqoop and Flume for data ingestion.

    Mastering real-time data processing using Spark: You will learn to do functional programming in Spark, implement Spark applications, understand parallel processing in Spark, and use Spark RDD optimization techniques. You will also learn the various interactive algorithm in Spark and use Spark SQL for creating, transforming, and querying data form.

    As a part of the course, you will be required to execute real-life industry-based projects using CloudLab. The projects included are in the domains of Banking, Telecommunication, Social media, Insurance, and E-commerce.  This Big Data course also prepares you for the Cloudera CCA175 certification.

  • What are the course objectives?

    • Software Developers and Architects
    • Analytics Professionals
    • Senior IT professionals
    • Testing and Mainframe professionals
    • Data Management Professionals
    • Business Intelligence Professionals
    • Project Managers
    • Aspiring Data Scientists
    • Graduates looking to build a career in Big Data Analytics
    Prerequisite:
    • As the knowledge of Java is necessary for this course, we are providing a complimentary access to “Java Essentials for Hadoop” course 
    • For Spark we use Python and Scala and an Ebook has been provided to help you with the same
    • Knowledge of an operating system like Linux is useful for the course

  • What is CloudLab?

    CloudLab is a cloud-based Hadoop and Spark environment lab that Simplilearn offers along with the course to ensure a hassle-free execution of the hands-on project which you need to complete in the Hadoop and Spark Developer course.

    With CloudLab, you do not need to install and maintain Hadoop or Spark on a virtual machine. Instead, you’ll be able to access a preconfigured environment on CloudLab via your browser. This provides a very strong semblance to what companies are using today to increase their Hadoop installation scalability and availability.

    You’ll have access to CloudLab from the Simplilearn LMS (Learning Management System) for the duration of the course. You can learn more about CloudLab by viewing our CloudLab video.

  • What projects are included in this course?

    The course includes 5 real-life, industry-based projects. CloudLab has been provided for a hassle-free execution of these projects. Successful evaluation of one of the following 2 projects is a part of the certification eligibility criteria.

    Project 1
    Domain- Banking
    Description- A Portuguese banking institution ran a marketing campaign to convince potential customers to invest in bank term deposit. The marketing campaigns were based on phone calls. Often, the same customer was contacted more than once through phone, in order to assess if they would want to subscribe to the bank term deposit or not. You have to analyze the data collected through the marketing campaign.

    Project 2
    Domain- Telecommunication
    Description- A mobile phone service provider has introduced a new Open Network campaign. The company has invited the users to raise a request to initiate a complaint about the towers in their locality if they face issues with their mobile network. The company has collected the dataset of users who had raised the complaint. The fourth and the fifth field of the dataset has latitude and longitude of users which is an important information for the company. You have to find this information of latitude and longitude on the basis of available dataset and create three clusters of users with k-means algorithm.

    For further practice, we have three more projects to help you start your Hadoop and Spark journey.

    Project 3
    Domain- Social Media
    Description- As part of a recruiting exercise, a major social media company asked candidates to analyze data set from Stack Exchange.
    You will be using the data set to arrive at certain key insights.

    Project 4
    Domain- Website providing movie-related information
    Description-IMBD is an online database of movie-related information. IMBD users rate the movies and provide reviews. They rate the movies on a scale of 1 to 5; 1 being the worst and 5 being the best. The data set also has additional information, such as the release year of the movie. You have to analyze the data collected.

    Project 5
    Domain- Insurance
    Description-A US-based insurance provider has decided to launch a new medical insurance program targeting various customers. To help a customer understand the current realities and the market better, you have to perform a series of data analysis using Hadoop.

The overall experience has been great with Simplilearn. The course content is very thorough and easy to understand. Online classes are held on a regular basis with the terrific instructor who makes it much easier for us to understand the concepts. Real time examples make the content relatable for even a layman. Faster query resolution is provided. They have support ticketing system through which you can create a support ticket for any kind of queries to get a quick reply. Live chat sessions are also there to get real-time help. The course videos are designed in a very interactive way and the duration of videos is minimal to keep you interested in the topic. The cloud lab feature is also great for people who are not able to install the software on their own machines. The cloud lab allows you to complete your assignments and practice work there itself. In-depth information is provided about each topic and other course materials are also provided to help with complete learning. All in all, I will suggest to try out the courses provided by Simplilearn as they are excellent according to different certifications which are great for the professional career.
