Subject [jira] [Updated] (MAPREDUCE-2858) MRv2 WebApp Security
Date Tue, 25 Oct 2011 16:20:34 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2858?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Joseph Evans updated MAPREDUCE-2858:
-------------------------------------------

    Target Version/s: 0.23.0, 0.24.0  (was: 0.24.0, 0.23.0)
        Release Note: 
A new server has been added to yarn.  It is a web proxy that sits in front of the AM web UI.
 The server is controlled by the yarn.web-proxy.address config.  If that config is set, and
it points to an address that is different then the RM web interface then a separate proxy
server needs to be launched.

This can be done by running 

yarn-daemon.sh start proxyserver

If a separate proxy server is needed other configs also may need to be set, if security is
enabled.
yarn.web-proxy.principal
yarn.web-proxy.keytab

The proxy server is stateless and should be able to support a VIP or other load balancing
sitting in front of multiple instances of this server.

Sorry it was the Admin ACL that I removed not the principal.

> 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.
