## Step Three: Start the Zeppelin UI to launch jobs on your Spark cluster
|
||||
|
||||
The Spark driver is used to launch jobs into Spark cluster. You can read more about it in
|
||||
[Spark architecture](https://spark.apache.org/docs/latest/cluster-overview.html).
|
||||
The Zeppelin UI pod can be used to launch jobs into the Spark cluster either via
|
||||
a web notebook frontend or the traditional Spark command line. See
|
||||
[Zeppelin](https://zeppelin.incubator.apache.org/) and
|
||||
[Spark architecture](https://spark.apache.org/docs/latest/cluster-overview.html)
|
||||

|

|

## Step Four: Do something with the cluster
|
||||
|
||||
Use the kubectl exec to connect to Spark driver and run a pipeline.
|
||||
Now you have two choices, depending on your predilections. You can do something
|
||||
graphical with the Spark cluster, or you can stay in the CLI.
|
||||
|
||||
### Do something fast with pyspark!
|
||||
|
||||
Use the kubectl exec to connect to the Zeppelin driver and run a pipeline.
|
||||

## Known Issues With Spark
|
||||
|
||||
* This provides a Spark configuration that is restricted to the cluster network,
|
||||
meaning the Spark master is only available as a cluster service. If you need
|
||||
to submit jobs using external client other than Zeppelin or `spark-submit` on
|
||||
the `zeppelin` pod, you will need to provide a way for your clients to get to
|
||||
the
|
||||
[`examples/spark/spark-master-service.yaml`](spark-master-service.yaml). See
|
||||
[Services](../../docs/user-guide/services.md) for more information.
|
||||
|
||||
## Known Issues With Zeppelin
|
||||
|
||||
* The Zeppelin pod is large, so it may take a while to pull depending on your
|
||||
network. The size of the Zeppelin pod is something we're working on, see issue #17231.
|
||||
|
||||
* Zeppelin may take some time (about a minute) on this pipeline the first time
|
||||
you run it. It seems to take considerable time to load.
|
||||
|
||||
* On GKE, `kubectl port-forward` may not be stable over long periods of time. If
|
||||
you see Zeppelin go into `Disconnected` state (there will be a red dot on the
|
||||
top right as well), the `port-forward` probably failed and needs to be
|
||||
restarted. See #12179.
