Directory /tmp/hadoop-zhangjc/dfs/name is in an inconsistent state

按照官网手册安装完单机 Hadoop 集群（见我的另外一篇文章：搭建单节点Hadoop集群），电脑重启后，在启动 HDFS 时 NameNode 启动失败，出现以下错误信息：

$ sbin/start-dfs.sh 
Starting namenodes on [localhost]
pdsh@frin: localhost: ssh exited with exit code 1
Starting datanodes
Starting secondary namenodes [frin]

查看 NameNode 启动日志可以看到以下错误信息：

这是因为 HDFS 的元数据信息默认存储在临时目录 tmp 中，机器重启后这些临时目录会被清理掉。增加以下配置：

etc/hadoop/hdfs-site.xml

1
2

<property>
    <name>dfs.namenode.name.dir</name>
    <value>file:///home/zhangjc/frin/hadoop/dfs/name</value>
</property>

重新格式化 HDFS，并重启即可。
