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.

Hi Brian,
We are moving past the performance testing and onto failover testing.
I have a five-node cluster and created a PB and HTTP clustered client based on
the cook book. I tested out and everything seems to be working. Then I shutdown
one node in the cluster and all my tests failed. It seems like the PB and HTTP
cluster client connects to all configured nodes initially and will throw an
exception if any node is down. Does this defeat the purpose of clustering? In
my test, I have 10 threads, each creates a PB and HTTP cluster client and then
goes on to execute a series of tests. From the attached log file, you can see
every test thread is failing at connection the down node, even though there are
four other nodes that can do the work.
Also, is the failover automatic or we have to catch the connection refused
exception and creating a new client or just re-execute the method?
Is using a load balancer a better way to handle failover/load balancing issue?
Appreciate you insights and help.
Best regards,
