In CDH3u5, when the DataNode is Decommissioned, the DataNode progress will be shutdown by NameNode.
But In CDH4.3.1, when the DataNode is Decommissioned, the DataNode progress will be not shutdown by NameNode. When the datanode is Decommissioned, why the datanode is not automatically shutdown by NameNode in CDH4.3.1? Thanks, LiuLei
