Many cloud platforms and third-party service providers offer Hadoop as a service or VM/container image. This lowers the barrier of entry for those wishing to get started with Hadoop. In this hands-on lab, we will have the opportunity to deploy a single-node Hadoop cluster in a pseudo-distributed configuration. Doing so demonstrates the deployment and configuration of each individual component of Hadoop, getting us ready for when we want to start working with a multi-node cluster to separate and cluster Hadoop services. In this learning activity, we will be performing the following:

  • Installing Java
  • Deploying Hadoop from an archive file
  • Configuring Hadoop's JAVA_HOME
  • Configuring the default filesystem for Hadoop
  • Configuring HDFS replication
  • Setting up passwordless SSH
  • Formatting the Hadoop Distributed File System (HDFS)
  • Starting Hadoop
  • Creating files and directories in Hadoop
  • Examining a text file with a MapReduce job
What are Hands-On Labs?

Hands-On Labs are scenario-based learning environments where learners can practice without consequences. Don't compromise a system or waste money on expensive downloads. Practice real-world skills without the real-world risk, no assembly required.
