Permission denied: user=drwhopergroupdrwxrxrx

Use WEB to browse and operate the file system, and generally encounter permission problems

This is because the WEB browser is logged in as an anonymous user ( dr.who ), who only has read-only permissions, and most operations cannot be performed.

If you need to operate in the browser as a privileged user, you need to configure the following content in core-site.xml and restart the cluster

  <property>
    <name>hadoop.http.staticuser.user</name>
    <value>hadoop</value>
  </property>

However, this is not recommended

• HDFS WEBUI , read-only permission is very good, simple browsing is enough

• If high authority is given, there will be great security problems, resulting in data leakage or loss
