Robert Joseph Evans commented on MAPREDUCE-2858:
------------------------------------------------
Actually 160 of the findbugs warnings are unrelated 2 are related to caching,
and I could fix them, but it would slow things down unnecessarily. They deal
with caching of a value that is not locked every time it is accessed, if it is
up to date. I think that the other warning is one that already existed, but
some how is showing up now from WebApps, because all of the other warnings are
in code that was not touched by this patch.

> Key: MAPREDUCE-2858
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2858
> Project: Hadoop Map/Reduce
> Issue Type: Sub-task
> Components: applicationmaster, mrv2, security
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Luke Lu
> Assignee: Robert Joseph Evans
> Priority: Blocker
> Fix For: 0.23.0

> In MRv2, while the system servers (ResourceManager (RM), NodeManager (NM) and
> NameNode (NN)) run as "trusted"
> system users, the application masters (AM) run as users who submit the
> application. While this offers great flexibility
> to run multiple version of mapreduce frameworks (including their UI) on the
> same Hadoop cluster, it has significant
> implication for the security of webapps (Please do not discuss company
> specific vulnerabilities here).
> Requirements:
> # Secure authentication for AM (for app/job level ACLs).
> # Webapp security should be optional via site configuration.
> # Support existing pluggable single sign on mechanisms.
> # Should not require per app/user configuration for deployment.
> # Should not require special site-wide DNS configuration for deployment.
> This the top jira for webapp security. A design doc/notes of threat-modeling
> and counter measures will be posted on the wiki.
