### Verify Ranger HDFS Policy

Source: https://www.volcengine.com/docs/6410/72227

Use these shell commands to test if the configured Ranger policy correctly grants access to the specified HDFS directory for the hive user.

```shell
# 切换到管理员账号
su hdfs hdfs dfs -mkdir /user/ranger_test
hdfs dfs -chmod 000 /user/ranger_test
# 切换账号到 hive,因为已经配置了 hive 任意目录到权限，所以可以访问 /user/ranger_test
su hive
hdfs dfs -ls /user/ranger_test
```
