Journal Storage Directory /tmp/hadoop/dfs/journalnode/ns not formatted

项目场景：

项目背景：大数据集群断电关机,强制关机,非正常关机,没有关闭服务关机造成的问题:Journal Storage Directory /tmp/hadoop/dfs/journalnode/ns not formatted

报错：

原因分析：

不知道,搞坏了好几套集群了,大概就是journalnode没有同步数据

解决方案：

1.cd /tmp/hadoop/dfs/
2.所有节点的journalnode都备份一下(不用新建journalnode,万一没解决恢复原样)
  mv journalnode journalnode.bak
3.重新格式化 NameNode
hdfs namenode -initializeSharedEdits
4./tmp/hadoop/dfs/目录下就会自动生成journalnode
5.启动集群start-all.sh
