I'm attempting to restore Riak onto a new instance (single node, no ring). I rename the node and update the configurations using the riak-admin reip command. However, when I start Riak and once Yokozuna starts, Yokozuna drops the indexes that have been restored in the yz directory. Here is what I see in the logs:
2017-12-05 23:01:00.130 [info] <0.3554.0>@riak_kv_index_hashtree:build_or_rehash:1055 Starting AAE tree build: 91343852333181432387730302044767688728495783936

2017-12-05 23:01:11.205 [info] <0.3396.0>@yz_index:local_remove:315 Unloaded previous instance of index finder
Any idea how to prevent this from occurring?
I figured out the problem. I was missing the cluster_data directory. I needed that to able to restore the data with the indexes.
