> We used protected dirs to ensure that important data directories cannot be
> deleted by mistake. But protected dirs can only be configured in
> hdfs-site.xml.
> For ease of management, we add a way to get the list of protected dirs from
> a special configuration file.
> How to use.
> 1. set the config in hdfs-site.xml
> ```
> <property>
> <name>dfs.protected.directories.config.file.enable</name>
> <value>true</value>
> </property>
> <property>
> <name>fs.protected.directories</name>
> <value>[file:///path/to/protected.dirs.config]</value>
> </property>
> ```
> 2. add some protected dirs to the config file
> ([file:///path/to/protected.dirs.config])
> ```
> /1
> /2/3
> ```
> 3. done
