-------------------------------

As discussed in HDFS-1312, we need a jsp on datanode that shows local
filesystem usage information. Beyond that, do we need a centralized collection
mechanism, with which we can got alerts for unbalanced datanodes?
> Allow HDFS client to measure distribution of blocks across devices for a
> specific DataNode
