> 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?
