Yin,
IIUC, you need to set this option to True on your gluster volume to get
past this error.
Gluster experts can provide more info here.

Option: nfs.ports-insecure
Default Value: (null)
Description: Allow client connections from unprivileged ports. By
default only privileged ports are allowed. Use this option to enable or
disable insecure ports for a specific subvolume and to override the
global setting set by the previous option.

volume set <VOLNAME> <KEY> <VALUE> - set options for volume <VOLNAME>

eg: gluster volume set <volname> nfs.ports-insecure on
something like that.
