Luke Lu commented on MAPREDUCE-2858: ------------------------------------ @Allen: since everything go through the proxy the proxy will check any non-relative URLs against a whitelist, so redirect via http or html meta or whatever method is not an issue. I don't think you actually understand how this proxy would work. It authenticates the user and if the user is not the owner of AM, the filtering will happen. > 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 > Reporter: Luke Lu > Assignee: Luke Lu > 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. -- This message is automatically generated by JIRA.
