本文介绍了解决Hadoop中SecondaryNameNode出现异常的方法。首先需要停止Hadoop服务，接着删除临时目录中的SecondaryNameNode数据文件（路径可通过hadoop.tmp.dir获取），最后重新启动Hadoop服务即可解决问题。

We need to stop the hadoop services first , and then delete the tmp secondary namenode directory (hadoop.tmp.dir will tell the path for secondary namenode data directory). After this, start the services again and the issue will be fixed.

原先使用hadoop默认设置（hadoop1.2.1），secondarynamenode会正常进行备份，定时从namenode拷贝image文件到SNN。但是具体SNN备份的时间周期和log文件的大小无法定制，后来楼主就修改了SNN的设置，将fs.checkpoint.period修改为3600s,fs.checkpoint.size修改为64兆。在core-site....

一、事情的起因： 本来是按照手册顺利的安装了全分布式集群，并且能够正常启动集群，集群又、有三台集群，hadoop102 是master，其他2台是node，secondarynamenode配置在hadoop104上， 一次手痒不小心在master下的root账户下启动了集群，然后就发现在hadoop104的一般账户下不能启动secondarynamenode了，但是在hadoop104的ro...
HDFS Namenode故障恢复：从元数据损坏到集群重启全指南

HDFS的Namenode是整个分布式文件系统的“大脑”——它存储着所有文件的元数据（文件名、路径、权限、块位置等），协调Datanode的读写操作。一旦Namenode故障（比如元数据损坏、服务器宕机），整个HDFS集群会完全不可用：既无法读取 existing 文件，也无法写入新文件。新手可能会慌不择路，误操作导致元数据彻底丢失；有经验的工程师也可能因为对“元数据恢复逻辑”理解不深，踩中隐藏的坑（比如恢复后文件块丢失）。本文的目标是把Namenode故障恢复变成可复制的“流程化操作”你将学会。

bug：ERROR org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode: Exception in doCheckpoint

hadoop.tmp.dir配置参数指定hdfs的默认临时路径，这个最好配置，如果在新增节点或者其他情况下莫名其妙的DataNode启动不了，就删除此文件中的tmp目录即可。不过如果删除了NameNode机器的此目录，那么就需要重新执行NameNode格式化的命令。（我觉得这其实就是因为上面那个原因造成的。按照上面那个第二个方法去做就行了。）
