The answer is there, create a client config with N pooled connections to
your load balancer whatever you are using, I know HA proxy supports the
PBC config (TCP based) which is faster than HTTP client, and hence my
recommendation.
Say, a non-clustered client config with N connections to balancer_host
at 8087 and your balancer_host connected to EACH node, that's the way to
go, the rest is about the CAP level you want to support which will
impact your performance vs integrity. Up to you.

Hi,
The node is OK and not down.
I have a way to do load balancing externally to JAVA Client.
I am evaluating Riak for using in my company and want to measure
maximal throughput vs single node.
Thanks,
Pavel

That question has been answered few times, here is my old answer:
Hi,
It is the Java client which to be honest, doesn't handle well one node
going down, so, for example, in my company we use HA proxy for that, here is
a starting configuration:https://gist.github.com/1507077
Once we switched to HA proxy we just use a simple client without cluster
config, so the Java client doesn't know anything about the load balancing
going on. It works well, I can upgrade and restart servers without our Java
application be complaining.
Regards,
Guido.

well I asked same question few days ago (maybe 2 weeks form
now) and
the answer was that yes sharing client is thread safe and all you
should do is to create new bucket instance on every request
