Big Data Overview: Lab Setup Instructions (For Eclipse plus Tomcat)

Below are the standard requirements for this course. If you have any questions or issues, please contact us.

Important Note: Student lab files are required on each computer used for the course. The links for these are not in this lab setup, and you should receive them separately.

Other notes:

• It’s a good idea to keep downloaded software install files on the machines during the class in case of problems that require a re-install.
• Cloning a setup is generally not a problem. If it is, we’ll mention it in the software section (for example, much of the IBM/RAD-WAS software can be problematic in this regard).

Install Java Development Kit – JDK 1.8 Update 411

• Note that any relatively recent JDK1.8 version is fine.
• Note that you'll need a free Oracle logon to download the JDK.
• From https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html find the latest Java 8 release installer file for your OS
  • Windows 64 bit: e.g. jdk-8u411-windows-x64.exe (Almost certainly this is the one you want. 32-bit Windows OS installs are now rare).
• Click the link for the installer file, accept the license agreement, enter your login credentials, and download the installer.

• Run the installer and take all defaults.

• Create or modify environment variables as appropriate for your OS. This will add an environment variable JAVA_HOME, and modify your path to include the jdk bin folder
  • JAVA_HOME:
    • Right click My Computer and choose Properties > click the Advanced tab > click the Environment Variables button
    • In the bottom half of the dialog, click New to add a new System variable
    • Variable name: JAVA_HOME (this is case-sensitive)
    • Variable value: C:\Program Files\Java\jdk1.8.0_411 (or adjust to the actual path where you installed the JDK and your JDK version – please double-check this path – probably best to copy and paste it)
    • Click OK
  • Path:

    %JAVA_HOME%\bin;

    • Find this existing entry in the bottom half of the Environment Variables button, and click Edit
    • Click in the Variable value field and move your cursor all the way to the left (pressing Home on your keyboard should do this quickly for you)
    • Check whether the value below is already present, or add it at the beginning if necessary (make sure you get all of this, including the trailing semicolon, with no spaces):

  • Click OK repeatedly (likely in 3 different dialogs) until all the dialogs close.

• Open a terminal prompt type the below, and press Enter

  javac -version

  You should get a message that tells you the version. If the command is not found, you did something wrong.

• Close the terminal prompt. You’re done installing Java
