Hi,
I have Couchbase cluster of 4 nodes (2.5), using Java client SDK (1.4.4),
Java 7.
My client application on start up successfully connected to all 4 nodes.
*My client code:*
CouchbaseConnectionFactoryBuilder cbfb = new
CouchbaseConnectionFactoryBuilder();
CouchbaseClient couchbaseClient= null;
List<URI> uris = new ArrayList<URI>();
uris.add(URI.create("http://node7:8091";));
uris.add(URI.create("http://node8:8091";));
uris.add(URI.create("http://node9:8091";));
uris.add(URI.create("http://node10:8091";));
CouchbaseConnectionFactory cbcf = cbfb.buildCouchbaseConnection(uris,
"bucket1", "");
couchbaseClient = new CouchbaseClient(cbcf);
while(true) {
try {
Thread.sleep(5000);
o = couchbaseClient.get("04849b37-f1b0-4772-960a-dd5fd13d8ea8");
}
catch(Exception e) {
System.out.println("exception:"+getStackTrace(e));
}
}
I stop all nodes for 10 minutes and start them all.
*On client side I see exception but on Couchbase web console I see that all
nodes is up*

After client application restart look up by key runs properly without any
exception.
I expect full connection recovery on client side after cluster
failure/restart.
Thanks,
David.
