Craig Condit commented on YARN-8623:
------------------------------------
I've been looking into this one a bit, and unfortunately,
apache/hadoop-runner:latest doesn't seem to be a viable option. That image
contains an ENTRYPOINT which attempts to sudo (without a password), resulting
in the container failing to run when the launching UID != 1000 (the hadoop user
within the container). This can be seen via docker logs as:
{code:java}
sudo: unknown uid 1004: who are you?{code}
I see two potential paths forward:
# Update the documentation to be more generic (maybe your-docker-image:latest
instead of images/hadoop-docker:latest), and refer to the existing
documentation on preparing an image for use with Hadoop.
# Create (and maintain going forward) an official Apache Hadoop docker image
pre-configured to work out of the box, or at least as a starting point for
user-created images.

> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Craig Condit
> Priority: Minor
> Labels: Docker
>
> The example Docker image given in the documentation
> (images/hadoop-docker:latest) does not exist. We could change
> images/hadoop-docker:latest to apache/hadoop-runner:latest, which does exist.
> We'd need to do a quick sanity test to see if the image works with YARN.
