> DatanodeReport returns both live and dead datanodes and there is no way to distinguish
live nodes from dead nodes. But some applications are interested in only live datanodes. 
I propose that instead of haveing one datanodeReport, dfs supports two reports: liveDatanodeReport
and deadDatanodeReport.
