How do I make a Hazelcast client wait for the server to start up?

Question

I have a Hazelcast client application which will sometimes be started before any server in the cluster. Before I start building this myself.

Is there any built in support in Hazelcast to make the client wait for the cluster to start up and then connect to it?

Answer 1

Yes you can set the connectionAttemptLimit on the ClientConfig.

connectionAttemptLimit: the maximum numbers of times to try the addresses to connect to the cluster, defaults to 2. When a client starts or a the client looses connecting with the cluster, it will try to make a connection with one of the cluster member addresses. In some cases a client can’t connect to these addresses, e.g. the cluster is not yet up or not reachable. Instead of giving up, one can increase the attempt limit to create a connection. Also have a look at the connectionAttemptPeriod.

Answer 2

I found this and it worked for me: <hz:network connection-attempt-limit="50" connection-attempt-period="5000" connection-timeout="1000" redo-operation="true"> <hz:member>
