我更新了data.path中的elasticsearch.yml条目以指向新位置。但是，在尝试重新启动Elastic时，我现在收到以下错误：
Starting elasticsearch: Exception in thread "main" java.lang.IllegalStateException: Unable to access 'path.data' (/etc/lib/stuff)

为了调试，我尝试将data.path从默认的var/lib/elasticsearch移动到/var/lib/stuff。
据我所知，用户，组和权限在这两个目录中匹配：
$ ls -l /var/lib/
drwxr-xr-x 3 elasticsearch elasticsearch 4096 Jan 11 10:50 elasticsearch
...
drwxr-xr-x 2 elasticsearch elasticsearch 4096 Jan 13 10:54 stuff
...
那么为什么Elastic会抛出AccessDenied例外？
如果我删除了我的自定义data.path，那么它会重新开始工作。我错过了什么吗？
