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: docker/for-mac#6620 (comment)

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

[flowy0]

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

/reopen I believe this is still an issue. ghcr.io/googlecloudplatform/spark-operator:v1beta2-1.3.8-3.1.1 is available only as an amd64 image, necessitating emulation on non-amd64 systems. And it seems QEMU 7.4 does not properly emulate a system call or similar.

Is there any reason the project does not publish arm64 images?
