Build

The view can be built as a maven project.

The build will produce the view archive.

target/capacity-scheduler-???-SNAPSHOT.jar

Place the view archive on the Ambari Server and restart to deploy.

cp capacity-scheduler-???-SNAPSHOT /var/lib/ambari-server/resources/views/
ambari-server restart

Deploying the View

Use the Ambari Vagrant setup to create a cluster:

Deploy the Capacity Scheduler view into Ambari.

Local Development

If you want to perform UI development without having to build and redeploy the view package, you can mount the build target output as a symlink to your vagrant instance. UI changes will be picked-up with a browser refresh.

After building and deploying the View, delete the view work directory on the Ambari Server.

cd /var/lib/ambari-server/resources/views/work
rm -rf CAPACITY-SCHEDULER\{0.3.0\}/

Create a symlink from the vagrant machine running your Ambari Server to your local machine.

ln -s /vagrant/ambari/contrib/views/capacity-scheduler/target/classes/ CAPACITY-SCHEDULER\{0.3.0\}

Restart Ambari Server, login and browse to the view.

ambari-server restart
http://c6401.ambari.apache.org:8080/#/main/views/CAPACITY-SCHEDULER/0.3.0/CS_1

If you modify the view UI code on your machine and re-build, the UI will pickup the changes on browser refresh.
