Hello, I have one simple question about node creation. Java api according it creates like: Node node = nodeBuilder().client(true).node(); Client client = node.client(); My question is: when your application will create clien node to connect and consult index to master server node, you always must close node and client after each search query? like: client.close(); node.close(); Or only i must close client? Advance thank you very much. ---

I suggest to close the client and the node only when your application stops.

what if my jvm crashes and I don't close the client. How do the other nodes react. I assume (hope) everything will be ok? thanks!

Yes, either the socket will be broken and immediately identified as a failed node, or the fault detection process will identify it.
