Please add or free up more resources then turn off safe mode manually. NOTE: If you turn off safe mode before adding resources, the NN will immediately return to safe mode. Use "hdfs dfsadmin -safemode leave" to turn safe mode off. ``` ### 解决 可能是磁盘快占满了，执行下面命令查看： 查看磁盘占用大小： ``` df -hl ``` ``` du -sh / ``` 原文出处：http://www.malaoshi.top/show_1IX2FzsdlA9g.html
