2016-12-12 18:33:15,465 WARN org.apache.hadoop.hdfs.server.common.Storage: java.io.IOException: Incompatible clusterIDs in /home/liusen/program/hadoop/share/hadoop/hdfs/datanode: namenode clusterID = CID-fb55d5eb-447a-4248-af41-9b99d874bc33; datanode clusterID = CID-092abfe0-98ce-4236-b0c0-97de0350e29d

問題解決方法如下：
首先格式化namenode（命令百度）
把NN裡面的tmp資料夾下面的VERSION檔案下面的clusterID拷貝到子節點下面的新建的hdfs下面的datanode和namenode下面的VERSION檔案下面的clusterID。
