Apache Lens

Apache Lens is a unified Analytics Platform. Lens aims to cut the Data Analytics silos by providing a single view of data across multiple tiered data stores and optimal execution environment for the analytical query.

Prerequisites : Apache Lens requires JDK(1.7) and Apache Maven(3.x) to be installed for the build. Build does not pass with JDK(1.8) yet. JAVA_HOME is required for running tests.

Confirm versions :

java -version

mvn --version

echo ${JAVA_HOME}

Additionally MAVEN_OPTS can be configured as :

export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m"

Build the project :

mvn clean package
