[jira] [Commented] (YARN-8623) Update Docker examples to use image which exists

["Eric Yang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-8623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16618157#comment-16618157 ] 

Eric Yang commented on YARN-8623:
---------------------------------

The discussion has not converged toward using apache/hadoop-runner image for documentation example due to limitation of the current images that might not work in most YARN environment.  For us to converge to use apache/hadoop-runner image in documentation, the images must be enhanced to do the following:

#  Hadoop runner image intelligently supports user management using sssd socket when running with normal user uid/gid.
#  Java and Hadoop binaries are part of hadoop-runner image to ensure the version control of the hadoop docker images are self contained for binaries.  (level set expectation, no actual code changes).

Do we agree on the docker image enhancement to converge for documentation updates?  If agreed upon, I will open JIRA to enable sssd support in hadoop-runner image.  If not agreed upon, we can close this as no plan to fix.

> 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.
