<pre><code>spark version:2.3.3
kubernetes version :v1.15.3

I'm getting the below exception while running spark code with kubernetes.
Even though I assigned the role and rolebinding and trying, still giving same exception. Please suggest solution if anyone had got such kind of exception.

I had created role and rolebinding and tried but it can't help me.
Even I did reset kubernetes and tried again by reseting it but still facing same issue.
I can't  find  out the solution for this on google.

Below spark submit command I'm using :

nohup bin/spark-submit --master k8s://https://192.168.154.58:6443 --deploy-mode cluster --name spark-pi --class org.apache.spark.examples.JavaSparkPi --conf spark.kubernetes.authenticate.driver.serviceAccountName=spark  --conf spark.executor.instances=1 --conf spark.kubernetes.container.image=innoeye123/spark:latest local:///opt/spark/examples/jars/spark-examples_2.11-2.3.3.jar &gt; tool.log &amp;

    spark.stop();
  }
}


Expected result : spark-submit command should run smoothly and terminate it successfully by creating a successful pod.

<p>Spark 2.4.4 or Spark 3.0.0 with k8s 1.18 got same error for me.</p>
<p>You can try to use http instead of https API.</p>
<p>Go to your Master k8s and create an HTTP access point  :</p>
<pre><code>kubectl proxy --address=ip_your_master_k8s --port=port_what_you_want --accept-hosts='^*' --accept-paths='^.*' --disable-filter=true

</code></pre>
<p>and then :</p>
