Starting riak previously:

(riak@127.0.0.1)1> setup:find_env_vars(exometer_defaults).
[{riak_core,[{['_'],
              histogram,
              [{options,[{histogram_module,exometer_slot_slide},
                         {keep_high,500}]}]}]}]
(riak@127.0.0.1)2> setup:find_env_vars(exometer_predefined).
[]

Starting riak with this branch:

(riak@127.0.0.1)1> exometer_util:find_env_vars(exometer_defaults).
[{riak_core,[{['_'],
              histogram,
              [{options,[{histogram_module,exometer_slot_slide},
                         {keep_high,500}]}]}]}]
(riak@127.0.0.1)2> exometer_util:find_env_vars(exometer_predefined).

Sorry if this is irrelevant but is this related to a brand new node being started for the first time with a distributed_cookie other than "riak"?
If so, a work around we've been using is to run sudo riak chkconfig first to make a set of pre-generated app.config and vm.args which appear to be read by the application with the issue when you actually start Riak and thus prevent the error from happening.
