------------------------------
SUCCESS: Integrated in Hadoop-trunk-Commit #6878 (See

> {{MiniDFSCluster}} allows the caller to set the number of storage locations
> per DataNode. If this number is set higher than 2, and if the cluster is
> configured with more than 1 DataNode, then the calculation of the storage
> directory paths will be incorrect. Multiple DataNodes will attempt to use
> the same storage directory, and one of them will fail while trying to acquire
> the file lock.
