@ayushtkn Thanks for the review! I agree that its better to cleanup the test
directory in `@After`. I have addressed the changes you've suggested.

> 2 tests are not idempotent and fails upon repeated execution within the same
> JVM instance due to self-induced state pollution. Specifically, these tests
> try to make the directory TEST_ROOT_DIR and write to it. The tests do not
> clean up (remove) the directory after execution. Therefore, in the second
> execution, TEST_ROOT_DIR would already exist and the exception `Could not
> create test dir` would be thrown. Below are the 2 non-idempotent tests:
> * org.apache.hadoop.mapred.TestOldCombinerGrouping.testCombiner
> * org.apache.hadoop.mapreduce.TestNewCombinerGrouping.testCombiner
