How to setting ADVANCED.CONFIG in MAC? [JIRA: RCS-388]

[hi-T0day]

I read the Fast-track in RIAK-CS and new an ADVANCED.CONFIG in riak-cs/etc.
But it always error. The error is below :
2017-03-20 20:05:08.182 [critical] <0.336.0>@riak_kv_app:start:107 storage_backend riak_cs_kv_multi_backend is non-loadable.
2017-03-20 20:05:08.182 [error] <0.335.0> CRASH REPORT Process <0.335.0> with 0 neighbours exited with reason: {invalid_storage_backend,{riak_kv_app,start,[normal,[]]}} in application_master:init/4 line 133

ADVANCED.CONFIG is like this:
[
{riak_kv, [
{add_paths, ["/MYHOME/riak-cs-2.1.1/lib/riak_cs-2.1.1/ebin"]},
{storage_backend, riak_cs_kv_multi_backend},
{multi_backend_prefix_list, [{<<"0b:">>, be_blocks}]},
{multi_backend_default, be_default},
{multi_backend, [
{be_default, riak_kv_eleveldb_backend, [
{total_leveldb_mem_percent, 30},
{data_root, "/MYHOME/riak-2.2.1/data/leveldb"}
]},
{be_blocks, riak_kv_bitcask_backend, [
{data_root, "/MYHOME/riak-2.2.1/data/bitcask"}
]}
]}
]}
].
Can any one help me?
