[tpj11]

在安装Hadoop-2.4.0的过程中，要hdfs namenode -format 但却出现错误，请问要如何提高权限?????
环境是Ubutu 14.04。

$ hadoop fs -chmod 777 /

[WL135266]

$ hadoop fs -chmod -R 777 /

[tchqiq]

sudo -i 刚玩 就先切换到root身份做所有事情吧。。。

引用 3 楼 csdalijingang 的回复:

$ hadoop fs -chmod -R 777 /

你这也太狠了吧，谁敢要你这样的程序员 hdfs启动时需要在${hadoop.log.dir}指定的目录（默认为安装目录下logs文件夹）下记录日志，所以只需要把这个文件夹的权限放开就行了 可参考： http://jiacai2050.github.io/blog/2014/07/17/installation-of-cdh-5-0-2-tar-gz-with-high-availability/

如何解决的，我遇到的问题和你一样，求解

[qq_14941653]

我解决了，是因为 /usr/local/hadoop_store/dfs/namenode/current没有权限，我们要到root目录下，然后给这个文件赋予权限 chown -R ubuntu:ubuntu / /usr/local/hadoop_store，因为每个人的用户名可能不一样，所以这里的ubuntu要更改为自己的
