On your server that you want the mount point, install 'fuse' and 'fuse-libs' from the BaseRepo.
# yum install -y fuse
# yum install -y fuse-libs
Then Install the RPMs you downloaded (in this order)
# rpm -Uvh hadoop-0.20-libhdfs-0.20.2+923.142-1.x86_64.rpm
# rpm -Uvh hadoop-0.20-fuse-0.20.2+923.142-1.x86_64.rpm
# mkdir /mnt/fuse
# hadoop-fuse-dfs dfs://(namenode-hostname)
Done!
The default port for a namenode is 8020
