HPCC4J and HPCC Kubernetes Clusters

Utilizing HPCC4J with containized HPCC Systems clusters requires some additional local configuration steps. These configuration steps are documented here: Using HPCC4j with HPCC on a Kubernetes Cluster

Build

These projects are configured to be built using Maven. To build the projects using Maven, navigate to the base directory of each project and issue the following command:

mvn install

NOTE: hpcccommons, wsclient, dfsclient, and spark-hpcc are controlled via the top-level maven pom file and can be built via a single command. All sub-projects can be built individually using the pom file in each sub-project directory

For more information on how to use Maven see http://maven.apache.org
