----------------------------------------
Summary: spark-submit on kubernetes cluster does not recognise k8s
--master property
Key: SPARK-27059
URL: https://issues.apache.org/jira/browse/SPARK-27059
Project: Spark
Issue Type: Bug
Components: Kubernetes
Affects Versions: 2.4.0, 2.3.3
Reporter: Andreas Adamides
I have successfully installed a Kubernetes cluster and can verify this by:
{{C:\windows\system32>kubectl cluster-info Kubernetes master is running at
https://<ip>:<port> KubeDNS is running at
https://<ip>:<port>/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy}}
Then I am trying to run the SparkPi with the Spark I downloaded from
[https://spark.apache.org/downloads.html] .(I tried versions 2.4.0 and 2.3.3)
{{spark-submit --master k8s://https://<ip>:<port> --deploy-mode cluster --name
spark-pi --class org.apache.spark.examples.SparkPi --conf
spark.executor.instances=2 --conf
spark.kubernetes.container.image=gettyimages/spark
c:\users\<username>\Desktop\spark-2.4.0-bin-hadoop2.7\examples\jars\spark-examples_2.11-2.4.0.jar}}
I am getting this error:
{{Error: Master must either be yarn or start with spark, mesos, local Run with
--help for usage help or --verbose for debug output}}
I also tried:
{{spark-submit --help}}
to see what I can get regarding the *--master* property. This is what I get:
{{--master MASTER_URL spark://host:port, mesos://host:port, yarn, or local.}}
According to the documentation
[[https://spark.apache.org/docs/latest/running-on-kubernetes.html]] on running
Spark workloads in Kubernetes, spark-submit does not even seem to recognise the
k8s value for master. [ included in possible Spark masters:
[https://spark.apache.org/docs/latest/submitting-applications.html#master-urls]
