----------------------------------------
Dupe of MAPREDUCE-2955?
> Update tests to not use MiniMRCluster Internally, and filter out duplicate
> tests
> --------------------------------------------------------------------------------
>
> Key: MAPREDUCE-4118
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4118
> Project: Hadoop Map/Reduce
> Issue Type: Test
> Components: test
> Affects Versions: 2.0.0, 3.0.0
> Reporter: Robert Joseph Evans
>
> There are a number of tests from MRV1 that are being pulled into MRV2. Many
> of these tests use MiniMRCluster, but the MiniMRCluser shim was added so that
> projects like Oozie and Pig can have a single test that will work for either
> Yarn or MRV1. Internally our tests are never going to go back to be run on
> MRV1 so we should update them to use the new code.
> Also there are some places where older tests and newer tests are almost
> duplicates of one another, or where the same results are archived through
> through mock objects. For the sake of runtime of the tests it would be
> better to remove some of these duplicates.
