PR_SET_CHILD_SUBREAPER is unavailable on this platform

[hongbo-miao]

I have a local k3s Kubernetes created by Rancher Desktop on MacBook Pro with M1 chip.

I try to install spark-on-k8s-operator by

helm repo add spark-operator https://googlecloudplatform.github.io/spark-on-k8s-operator
helm install spark spark-operator/spark-operator --namespace spark-operator --create-namespace

However, I got the error for the pod spark-spark-operator-6964986646-5vctk:

++ id -u

[FATAL tini (1)] PR_SET_CHILD_SUBREAPER is unavailable on this platform. Are you using Linux >= 3.4?

Any idea? Thanks! 😃

I'm having the same issue on colima

This comment explains the root cause of the issue: https://github.com/docker/for-mac/issues/6620#issuecomment-1694380189

It seems that this is triggered by the Spark container image using tini -s in the entrypoint.sh script, e.g. for 3.5.0: https://github.com/apache/spark-docker/blob/master/3.5.0/scala2.12-java11-ubuntu/entrypoint.sh

How can we solve this and get the setup in local. It is failing with latest rancher desktop

If you use colima with rosetta emulation or with an amd profile, it should resolve. I previously had this error. See details at Rosetta 2 emulation

#AMD profile
colima start --profile amd --arch amd --cpu 4 --memory 8 --disk 80

# or rosetta emulation
colima start --arch aarch64 --vm-type=vz --vz-rosetta --cpu 4 --memory 8 --disk 80
