      Description

      DatanodeCluster fails to start with NPE in MiniDFSCluster.

      Looks like a simple bug in MiniDFSCluster#determineDfsBaseDir - missing check for null configuration.

      Also included are a few improvements to DataNodeCluster, details in comments below.

        Thanks for the quick review Jing! Trivial update to patch to fix a typo in SimulatedStorage.

        Will commit once I have a Jenkins +1.

        Withdrawing the patch for now. There are other bugs in DatanodeCluster.

        Will submit a combined patch later.

        It looks like DataNodeCluster has not been used with Hadoop 2.0 in a while since I ran into numerous issues. I think I got most of them and I can now bring up a simple test cluster with a real NN and simulated DNs.

        Attaching a patch with the following fixes:

        1. MiniDFSCluster now handles null configuration when starting simulated Datanodes.
        2. MiniDFSCluster#injectBlocks accepts an optional BlockPoolId. If none is supplied then it tries to query it from the in-process NameNode i.e. existing behavior.
        3. DataNodeCluster accepts BlockPoolId on command line and passes it to injectBlocks
        4. DataNodeCluster optionally accepts SimulatedDnCapacities on the command line and passes it to startDataNodes. If none is supplied then it uses the existing default from SimulatedFSDataset.
        5. DataNodeCluster must wait after starting the DNs and before injecting blocks to allow the storage initialization to complete.
        6. BlockPoolId is printed when formatting NN.

        Rebase to resolve conflict with HDFS-5318 which was just committed. The conflict was fairly trivial, requiring the NN index to be passed to cluster.injectBlocks in TestReadOnlySharedStorage.

             // Inject the block into the datanode with READ_ONLY_SHARED storage
        -    cluster.injectBlocks(RO_NODE_INDEX, Collections.singleton(block));
        +    cluster.injectBlocks(0, RO_NODE_INDEX, Collections.singleton(block));
