Vinod K V commented on HADOOP-4830:
-----------------------------------
This particular JIRA should address the following:
- Write/improve utilities that will help the test-cases. This includes
-- enhancing
org.apache.hadoop.mapred.UtilsForTests.Waiting{Mapper|Reducer} so that the
tasks that can finish by signalling is controlled and is a subset of all the
tasks.
-- having a utility that makes a test to block and wait for a particular
number of tasks to be running and occupying a cluster's slots.
-- setting up a way to configure the capacity scheduler for the tests.
- Automate the tests related to queue capacities: submit jobs to different
queues simultaneously and see that capacities are honored
> Have end to end tests based on MiniMRCluster to verify that queue capacities
> are honoured.

> Key: HADOOP-4830
> URL: https://issues.apache.org/jira/browse/HADOOP-4830
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/capacity-sched
> Reporter: Vinod K V
>
> At present, we only have unit tests that make use of FakeTaskManager and that
> only test the proper functionality of capacity scheduler in isolation. Many
> issues unearthed recently proved that this is not enough and that it is
> required to have end-to-end tests so that real JT is brought into the picture
> and with that the interaction of the scheduler with JT. This issue along with
> few other related jiras should automate and replace the end-to-end tests that
> are now manually done by QA, using MiniMRCluster.
