Steve Loughran commented on YARN-4653:
--------------------------------------
thanks for the link ... hadn't seen that. nice. That's a document which should
be linked to, ideally even pulled into the hadoop site
I'm doing something less ambitious but equally important: explain to
application developers what they need. I'll change the title accordingly
> Document YARN security model from the perspective of Application Developers
> ---------------------------------------------------------------------------

> Key: YARN-4653
> URL: https://issues.apache.org/jira/browse/YARN-4653
> Project: Hadoop YARN
> Issue Type: Task
> Components: site
> Affects Versions: 2.7.2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> What YARN apps need to do for security today is generally copied direct from
> distributed shell, with a bit of [ill-informed
> superstition|https://steveloughran.gitbooks.io/kerberos_and_hadoop/content/sections/yarn.html]
> being the sole prose.
> We need a normative document in the YARN site covering
> # the needs for YARN security
> # token creation for AM launch
> # how the RM gets involved
> # token propagation on container launch
> # token renewal strategies
> # How to get tokens for other apps like HBase and Hive.
> # how to work under OOzie
> Perhaps the WritingYarnApplications.md doc is updated, otherwise why not just
> link to the relevant bit of the distributed shell client on github for a
> guarantee of staying up to date?
