Installing and configuring the standalone Hadoop package

To help verify and troubleshoot the Hadoop configuration and functionality on the computer that runs the basic runtime, install and configure the standalone Hadoop package. This step is optional.

Procedure

  1. Download the Hadoop v.2.2.0 distribution from the developer archive.

  2. Extract the contents of the hadoop-2.2.0.tar.gz file to a local folder.

  3. Configure the runtime to use the Hadoop native IO libraries. Follow the configuration instructions links in Related Tasks.

  4. Use one of the following commands to set the JAVA_HOME environment (Windows), or export the Java_HOME environment (Linux):

    • Windows: set JAVA_HOME=C:/Boomi_AtomSphere/Atom/Atom_name/jre
    • Linux: export JAVA_HOME=~/home/username/Bomi_AtomSphere/Atom/Atom_name/jre

  5. Point a variable to the JRE. You can reuse a private JRE if you deploy it with the basic runtime.

  6. Run Hadoop sample commands.
