Unable to install the operator with Helm3

[ityuhui]

Hi there
I want to install this operator in my k8s cluster with Helm3 but cannot succeed. Below is my step:

root@yuhuium:~# helm version
version.BuildInfo{Version:"v3.4.1", GitCommit:"c4e74854886b2efe3321e185578e6db9be0a6e29", GitTreeState:"clean", GoVersion:"go1.14.11"}

root@yuhuium:~# helm repo add incubator https://charts.helm.sh/incubator --force-update
"incubator" has been added to your repositories

root@yuhuium:~# helm install incubator/sparkoperator --namespace spark-operator --set sparkJobNamespace=default
Error: must either provide a name or specify --generate-name

root@yuhuium:~# helm install incubator/sparkoperator --namespace spark-operator --set sparkJobNamespace=default --generate-name

Could you please help check this ? Thanks.

You need to add the spark-operator namespace before applying the chart.

Thank you @jordanbailes !
The solution resolves my problem.

Hi @liyinan926
May I create a PR to update the readme/guide for this problem? I think somebody will have the same question in the future.

This will install the Kubernetes Operator for Apache Spark into the namespace spark-operator, if the namespce spark-operator does not exist, create it by manul, e.g.
kubectl create namespace spark-operator

But from Quick Start Guide, I can see

$ helm repo add incubator https://charts.helm.sh/incubator --force-update
$ helm install incubator/sparkoperator --namespace spark-operator --set sparkJobNamespace=default

Installing the chart will create a namespace spark-operator if it doesn't exist
