> If MiniDFSCluster constructor throws an exception, the cluster object is not 
> assigned, so shutdown() call not be called on the object.
> I saw in a recent Jenkins job where binding error threw an exception, and 
> later on the NPE of cluster.shutdown() hid the real cause of the test failure.
> HDFS-9333 has a patch that fixes the bind error.
