apache-spark startup error on alpine linux docker
Your problem is here in this line
The thing is that the alpine image comes with busybox, which is a replacement of many commands including nohup and ps. So alpine comes with a non-gnu nohup which cannot handle that --, and a ps which cannot handle -p.
So, install coreutils and procps packages before any call to apache spark scripts in order to have the version of nohup and ps that you need.
In Dockerfile or container command line:
RUN apk --update add coreutils procps
