Hadoop错误：Directory /tmp/hadoop-root/dfs/name is in an inconsistent state

Error message：

Directory /tmp/hadoop-root/dfs/name is in an inconsistent state: storage directory does not exist or is not accessible.

问题：

Linux系统每次重新启动后，hadoop不能正常启动namenode，需要重新格式化namenode才可启动

原因：

hadoop默认将namenode格式化在/tmp下，而这个目录当在重启时会被清空，所以报错。

解决方案：

vim /usr/local/hadoop/etc/hadoop/core-site.xml
#add code

          hadoop.tmp.dir
          /var/hadoop

#reformat namenode
hdfs namenode -format
