 Description  « Hide
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.
