> 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.
