Robert Joseph Evans updated MAPREDUCE-2858:
-------------------------------------------
Attachment: MR-2858.txt
MR-2858-branch-0.23.txt
I had upgraded the version of commons HttpClient unnecessarily and that made
some changes outside of the mapreduce project. It should all be fixed now. No
code changes were made, just the changes to two pom files were reverted.

> 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.
