Shane Kumpf commented on YARN-8623:
-----------------------------------
[~elek] - thanks, those details are helpful. It does appear
_apache/hadoop-runner_ is closer to what we want than I originally thought, but
the user setup clashes with our needs. With a goal of trying to provide a
working MR pi example, MapReduce expects to run (and write data) as the end
user (or a static local user, such as nobody, depending on config). I expect
Spark does as well.
Removing the use of sudo in the entrypoint script, gating that {{sudo chmod}}
in the starter script via an env variable, or opening up the sudo rules would
all seem to work to allow us to use this for YARN as well.
I think we should open a separate HADOOP Jira to discuss making the image work
for both cases if that makes sense to others. [~elek] [~ccondit-target]
thoughts?
> Update Docker examples to use image which exists
> ------------------------------------------------

> Key: YARN-8623
> URL: https://issues.apache.org/jira/browse/YARN-8623
> 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.
