Introduction About CDAP
CDAP is a 100% open-source framework for build data analytics applications
CDAP Sandbox allows you to build pipelines locally on your computer and it provides a great learning environment if you are new to CDAP. There are three varieties of CDAP sandbox that you can use locally; a Zip file archive, a VirtualBox VM, and a Docker image. If this is the first time you are setting up CDAP it may be easier to go with the Zip option as there are less components to configure and figure out. You can find the sandbox versions here: https://cdap.io/get-started/.
The instructions included here are for the Mac, but you should be ably to adapt them to your OS as well. The Zip archive will behave the sam way regardless of the operating system you are on. You can use homebrew, a handy package manager for the Mac, to install both Java and Node. I’ll spare you the details as to how to set up homebrew since there are many resources on the internet that you can refer to. Similar tutorials are available online for installing Java and Node for both Windows and Linux, so please refer to those resources for further instructions.
Step 1 — Install OpenJDK
CDAP 6.0 requires Java 8 or higher. Once installed make sure to validate that Java 8 has been installed correctly, and that the JRE is available from your path. You might have to add the JDK path to your user profile settings depending on your OS and current setup.
brew tap AdoptOpenJDK/openjdkbrew cask install adoptopenjdk8
Step 2 — Install NodeJS
Use an LTS version 10.16 or newer so that you have the latest supported LTS release.
brew install node@10
Step 3 — Install CDAP Sandbox
Download CDAP Sandbox 6.0 archive to your computer: https://downloads.cask.co/cdap-sandbox/cdap-sandbox-6.0.0.zip
Unzip the file to the folder of your choice, and change into the bin directory.
unzip cdap-sandbox-6.0.0.zipcd cdap-sandbox-6.0.0/bin
Start the CDAP Sandbox:
./cdap sandbox start
Once the service has started you will see the following message on the console. You can now open your browser and navigate to the local CDAP instance on your computer.
Starting CDAP Sandbox .............CDAP Sandbox started successfully.Connect to the CDAP UI at http://localhost:11011
Your CDAP instance will have no artifacts yet, so you will see an empty console screen.
