Robert Joseph Evans commented on MAPREDUCE-2858: ------------------------------------------------ @Alejandro The use of Hamlet would be by the proxy in displaying error and warning pages. It would not be required by the AM. We could add in a config to turn off the proxy/content rewriting all together. It would be a couple lines of change, but that would also mean that it would disable the solution for MAPREDCUE-3174 and anyone visiting a web page on the AM would not be redirected to the history server once the AM goes away. I am fine with doing that so long as the ramifications are understood. > MRv2 WebApp Security > -------------------- > > 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-branch-0.23.txt, > MR-2858.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. -- This message is automatically generated by JIRA.
