Hey. You can use the following commands to use mountable hdfs:
sudo yum install hadoop-hdfs-fuse
To set up and test your mount point in a non-HA installation:
$ mkdir -p <mount_point>
$ hadoop-fuse-dfs dfs://<name_node_hostname>:<namenode_port> <mount_point>
where namenode_port is the NameNode's RPC port, dfs.namenode.servicerpc-address.
To set up and test your mount point in an HA installation:
$ mkdir -p <mount_point>
$ hadoop-fuse-dfs dfs://<nameservice_id> <mount_point>
