CDAP Build repository

This repository is used for building a complete CDAP release.

This checks out CDAP, CDAP Security Extensions, and Cask Hydrator Plugins. The external application artifact repositories are located under app-artifacts, while security extensions are located under security-extensions, so CDAP should be built using -Dadditional.artifacts.dir=$(pwd)/app-artifacts -Dsecurity.extensions.dir=$(pwd)/security-extensions to include the additional projects in the CDAP Master packages.

Submodules and Git

This repository uses Git submodules to provide links to other repositories. Cloning this repository with --recursive will automatically initialize and checkout the additional repositories. These additional repositories are configured to track the correct remote branches for a given CDAP release. This repository will have the correct Git references stored for a particular tag. Checking out a tag to your working directory will update the submodule Git references to the ones used to build that tag.

If you cloned without using --recursive, you will need to initialize and checkout the submodules:

git submodule init
git submodule update

Starting with Git 1.8, it is possible to track remote branches in Git submodules. These branches have already been configured for each submodule, and the submodules can be updated to the head of that branch by appending --remote to the update command:

git submodule update --remote

Building a CDAP release

Compiling/Installing Apache Sentry 1.7.0

The CDAP Security Extensions require you to have Apache Sentry 1.7.0 JARs in your local Maven repository. These JARs are not available from Maven Central, so you may need to compile them. The correct branch for Sentry is included as a submodule under apache-sentry to make compilation easy.

mvn clean install -DskipTests -f apache-sentry

Installing CDAP API JARs

Compiling the artifacts requires first building and installing the CDAP API JARs into your local Maven repository.

export MAVEN_OPTS="-Xmx3056m -XX:MaxPermSize=128m"
mvn install -DskipTests -B -am -pl cdap/cdap-api -P templates
mvn install -DskipTests -B -am -f cdap/cdap-app-templates -P templates
