hadoopjournalns: NameNode has clusterId ‘CID-b82’ but storage has clusterId ‘CID-657
于是改成 tail -200 hadoop/logs/hadoop-xiaoye-namenode-ubuntu.log 这个命令，就可以看到出现这个错，NameNode has nsId 229502726 but storage has nsId 695608861 解决办法：原因分析： 是多次格式化namenode导致版本不一致，直接的办法是直接删掉hadoop/hadoop/目录下的data和name home/xiaoye/hadoop/journal/ns: NameNode has clusterId ‘CID-b824b399-e941-4982-a618-745373 9d3d55′ but storage has clusterId ‘CID-657e9540-2de9-43a2-bf91-199a4334b05a’ 于是还是修改上面的VERSION文件，把clusterId的值改成 storage
