I'm using the stock ntp binary from centos 7.x and I'm seeing this:

[ctrevino at ntp-eqix-sv5 ~]$ rpm -qa | grep ntp
[ctrevino at ntp-eqix-sv5 ~]$
[ctrevino at ntp-eqix-sv5 ~]$
[ctrevino at ntp-eqix-sv5 ~]$ ntpq -c mru
***Command `mru' unknown

    Are you using a standard dist?
     ntpq -c mru
    gives you the client list.
    The list length and size can be tailored:
    # mru [maxdepth count | maxmem kilobytes | mindepth count | maxage seconds | initalloc count | initmem kilobytes | incalloc count |
    incmem kilobytes]
      mru mindepth 5 maxdepth 100 initmem 1 incmem 1 maxage 86400
