Add HDFS system mount

After installing hadoop-hdfs-fuse and configuring the test mount, you can add a persistent HDFS system mount.

Open /etc/fstab and append information about the hostname, the NameNode port, and the mount point in the specified format.
The format is as follows:
```
hadoop-fuse-dfs#dfs://<name_node_hostname>:<namenode_port> <mount_point> fuse allow_other,usetrash,rw 2 0
```
For example:
```
hadoop-fuse-dfs#dfs://localhost:8020 /mnt/hdfs fuse allow_other,usetrash,rw 2 0
```
note

In an HA deployment, use the HDFS nameservice instead of the NameNode URI; that is, use the value of dfs.nameservices in hdfs-site.xml.
Test to make sure the mount point is working properly
```
mount <mount_point>
```

Your system is now configured to allow you to use the ls command and use that mount point as if it were a normal system disk.
