> 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
