On 5 node cluster when our servers boot our application (which runs on the
same nodes as riak and queries localhost) I got
Caused by: com.basho.riak.client.RiakRetryFailedException:

This happened during 2i query on node boot when Riak was not yet ready and
our app started to query Riak. In my case 2 nodes were slower with booting
I know about wait-for-service which probably should be used but I'm not
100% sure it would solve the problem.
I suppose my question is how can I make sure Riak is stable enough to start
querying via 2i
and avoid insufficient_vnodes_available?
Should I wait until at least allNodes-1 is up and running (wait-for-service
reorts Riak node ready?)
On a related note. Does 2i query uses primary vnodes to select covering set?
Regards
Daniel
