Robert Joseph Evans commented on MAPREDUCE-2858:
------------------------------------------------
I forgot to mention too, that a lot of the more complex operations that were
initially discussed here are not in this patch. There is no checksum
verification of JS in web pages. All this does is front the AM with a proxy
that strips out cookies and replaces them with a cookie indicating the user
that logged in through the proxy server. It also includes a new Filter for the
AM that will verify that all requests are coming from the proxy, and if not
redirect the client to go through the proxy.

> 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

> Attachments: MR-2858-branch-0.23.txt, MR-2858.txt

> 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.
