$ ./dev/dev2/bin/riak-admin join join dev1@127.0.0.1
The 'join' command has been deprecated in favor of the new 
clustering commands provided by 'riak-admin cluster'. To continue
using the deprecated 'join' command, use 'join -f'

$ ./dev/dev2/bin/riak-admin cluster
Usage: riak-admin cluster <command>

The following commands stage changes to cluster membership. These commands
do not take effect immediately. After staging a set of changes, the staged
plan must be committed to take effect:

    join <node>            Join this node to the cluster containing <node>
    leave                  Have this node leave the cluster and shutdown
    leave <node>           Have <node> leave the cluster and shutdown
    force-remove <node>    Remove <node> from the cluster without first
                           handing off data. Designed for crashed,
                           unrecoverable nodes

Staging commands:
    plan                   Display the staged changes to the cluster
    commit                 Commit the staged changes
    clear                  Clear the staged changes
