             Summary: Add admin acls to the Web UI
                 Key: SPARK-1891
                 URL: https://issues.apache.org/jira/browse/SPARK-1891
             Project: Spark
          Issue Type: Improvement
          Components: Web UI
    Affects Versions: 1.0.0
            Reporter: Thomas Graves
             Fix For: 1.1.0


In some environments you have multi-tenant clusters.  In those environments you 
sometimes have users, operations, support teams, and framework development 
teams (Spark, MR, etc developers).  When users have issues with their 
application they can ask for help from support teams or development.    In 
those cases you want the support team or development teams to be able to see 
the application UI so they can help the user debug what is going on without 
having to rerun the application.   

In order to more easily do that we can add a concept of "admin acls" to the UI. 
This is the list of users who are considered admins for the cluster and would 
always have permission to view the UI.  Generally this list would be set at the 
cluster level and picked up by anyone running on that cluster.

We should add "admin acls" to the Spark web ui to allow this.
