rahul k singh commented on HADOOP-4833:
---------------------------------------
TestUserLimits. java needs to cover following testcase:
Assuming userlimit being 25 , and 4 users are using the capacity. If 5th user
arrives and 4 users already using the capacity dont have the tasks to run on
those nodes, then in that case 5th user should be assigned some capacity to
execute his job.
> Have end to end tests based on MiniMRCluster to verify the correct behaviour
> of user limits

> We should have the following:
> - Basic user limit tests
> -- Submit jobs one after another and see that the jobs' usage honours
> user limits in the steady state.
> -- Submit jobs simultaneously and see that the jobs' usage honours user
> limits in the steady state.
> - User limit test with unequal share
> -- Submit jobs so that users get unequal share of the cluster. For e.g.
> configuring the cluster with min-user-limit of 40% and with 3 users should
> result in a distribution of 40%, 40% and 20%.
