<p>Please help with above requirement, Thanks</p>

<p>Assuming you're <strong>not</strong> using <a href="https://github.com/GoogleCloudPlatform/spark-on-k8s-operator" rel="nofollow noreferrer">spark on k8s operator</a> the master should be:</p>
<pre><code>k8s://https://kubernetes.default.svc.cluster.local
</code></pre>
<p>if not, you can get your master address by running:</p>
<pre><code>$ kubectl cluster-info
Kubernetes master is running at https://kubernetes.docker.internal:6443
</code></pre>
<p><strong>EDIT</strong>:
In spark-on-k8s <a href="https://spark.apache.org/docs/latest/running-on-kubernetes.html#cluster-mode" rel="nofollow noreferrer">cluster-mode</a> the <code>k8s://&lt;api_server_host&gt;:&lt;k8s-apiserver-port&gt;</code> should be provided (note that adding the port is must!)</p>
<p>In spark-on-k8s the role of &quot;master&quot; (in spark) is played by kubernetes itself - which is responsible to allocate resources for running your driver and workers.</p>
