Description

Running Junits that extend ClusterMapReduceTestCase generate lots of directories and folders without cleaning them up.

For example:

men test -Dtest=TestMRJobClient

generates the following directories:

- target
   -+ ConfigurableMiniMRCluster_315090884
   -+ ConfigurableMiniMRCluster_1335188990
   -+ ConfigurableMiniMRCluster_1973037511
   -+ test-dir
        -+ dfs
        -+ hadopp-XYZ-01
        -+ hadopp-XYZ-02 
        -+ hadopp-XYZ-03
