                 Key: LENS-619
                 URL: https://issues.apache.org/jira/browse/LENS-619
             Project: Apache Lens
          Issue Type: New Feature
            Reporter: Himanshu Gahlaut
            Assignee: Himanshu Gahlaut


Fair Usage Policy for using Lens

After a user has used the lens system beyond fair usage policy, he will get 
lens features in degraded mode. 

One of the forms of fair usage policy could be that at any point in time only N 
queries can be present in RUNNING state for a user. 
If N queries of a user are in RUNNING state, then a new query submitted by same 
user will stay in QUEUED state until one of the N queries in RUNNING state have 
moved to SUCCESSFUL, FAILED, OR CANCELLED state.
