# How does it work

![UML diagram](https://github.com/radanalyticsio/spark-operator/raw/master/docs/standardized-UML-diagram.png "UML Diagram")

# Quick Start

Run the `spark-operator` deployment: _Remember to change the `namespace` variable for the `ClusterRoleBinding` before doing this step_

```bash

kubectl apply -f manifest/operator.yaml

```

Create new cluster from the prepared example:

```bash

kubectl apply -f examples/cluster.yaml

```

After issuing the commands above, you should be able to see a new Spark cluster running in the current namespace.

```bash

kubectl get pods

NAME                               READY     STATUS    RESTARTS   AGE

my-spark-cluster-m-5kjtj           1/1       Running   0          10s

my-spark-cluster-w-m8knz           1/1       Running   0          10s

my-spark-cluster-w-vg9k2           1/1       Running   0          10s

spark-operator-510388731-852b2     1/1       Running   0          27s

```

Once you don't need the cluster anymore, you can delete it by deleting the custom resource by:

```bash

kubectl delete sparkcluster my-spark-cluster

```

# Very Quick Start

```bash

# create operator

kubectl apply -f http://bit.ly/sparkop

# create cluster

cat < OperatorHub` (make sure the namespace is set to `openshift-marketplace`).

### Troubleshooting

Show the log:

```bash

# last 25 log entries

kubectl logs --tail 25 -l app.kubernetes.io/name=spark-operator

```

```bash

# follow logs

kubectl logs -f `kubectl get pod -l app.kubernetes.io/name=spark-operator -o='jsonpath="{.items[0].metadata.name}"' | sed 's/"//g'`

```

Run the operator from your host (also possible with the debugger/profiler):

```bash

java -jar target/spark-operator-*.jar

```
