-------------------------------------------

    Attachment: MR-2858.txt
                MR-2858-branch-0.23.txt

Attaching patches for review.  The code changes in the two patches are identical.  The only differences between them is in the pom.xml and specifically in relation to how versions are specified.

> 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.
