Ring ownership after start

[kakoni]

So starting riak cluster as per documention
`DOCKER_RIAK_AUTOMATIC_CLUSTERING=1 DOCKER_RIAK_CLUSTER_SIZE=5 DOCKER_RIAK_BACKEND=leveldb make start-cluster``

After stabilization I'll check for ring ownership;
"ring_ownership": "[{'[email protected]',64}]",

Thats uncool.

So docker-enter into one of the nodes to see what riak-admin cluster plan shows

================================= Membership ==================================
Status     Ring    Pending    Node
-------------------------------------------------------------------------------
valid      20.3%     20.3%    '[email protected]'
valid      20.3%     20.3%    '[email protected]'
valid      20.3%     20.3%    '[email protected]'
valid      20.3%     20.3%    '[email protected]'
valid      18.8%     18.8%    '[email protected]'
-------------------------------------------------------------------------------
Valid:5 / Leaving:0 / Exiting:0 / Joining:0 / Down:0

Outstading changes, I'll commit them and check the status again

root@5ec57bbf8295:~# riak-admin cluster commit
Cluster changes committed
root@5ec57bbf8295:~# riak-admin cluster plan
There are no staged changes

All good. And obviously ring ownership also cool now
"ring_ownership": "[{'[email protected]',13},\n {'[email protected]',13},\n {'[email protected]',13},\n {'[email protected]',13},\n {'[email protected]',12}]",

So something with automatic_clustering fails here.

@kakoni, I had similar issues with unfinished cluster configuration. After digging into it I figured out that sometimes automatic_clustering.sh is executed too soon and 'cluster join' command returns "Node not found!" message. I wasn't able to come up with a quick fix for this issue and chose an alternative option: instead of joining the cluster from inside the container I'm doing it explicitly in start-cluster.sh, see bdb49dd and 83ff81f.

These changes give me consistently stable behaviour.

Hope this helps.
