我尝试在linux-mint上安装hadoop-3.2.0。一切都很好。java 11.0.2的安装方式如下：
$ java -version
java version "11.0.2" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.2+7-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.2+7-LTS, mixed mode)当我使用这个命令 hadoop version ，我得到这个错误：
$ hadoop version
log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: /usr/local/hadoop-3.2.0/logs/fairscheduler-statedump.log (No such file or directory)

This command was run using /usr/local/hadoop-3.2.0/share/hadoop/common/hadoop-common-3.2.0.jar看起来hadoop安装得很好，但是有点不对劲 log4j . 我可以请你帮我解决这个错误吗？
更新：我应该提到的是，我试图安装hadoop-3.2.0意味着hadoop-3.1.2之前的版本，一切看起来都很好。所以我想这是与JavaV11.0.2和hadoop-3.2.0相关的问题。

我也面临这个问题，但我认为这是由于不同的java版本。我最初安装了jdk11，但是更改了jdk8，因为hadoop3.x不兼容8之后的任何东西(https://cwiki.apache.org/confluence/display/hadoop/hadoop+java+versions).
然而，在改用jdk8之后，我仍然面临这个问题。提供的解决方案假设我们创建了一个hadoop用户，但我没有在服务器（工作计算机）上创建另一个用户的权限。
我应该将所有权更改为root吗？我确实有一些sudo特权。

我遇到了同样的问题，因为我是通过根用户安装hadoop，然后通过hadoop用户运行hadoop命令。我只是通过更改hadoop目录的所有者和组来解决这个问题。

我在/usr/local/hadoop中创建日志目录，并授予hadoop帐户权限。
