Hello, There was a bug [1] with one node thin client configuration, which is fixed now but was not released yet. You can try to add one more server address (the same address) as a workaround. For example:
ClientConfiguration cfg = new ClientConfiguration().setAddresses(hostName + ":" + portNumber, hostName + ":" + portNumber); [1] https://issues.apache.org/jira/browse/IGNITE-11649 вт, 2 июл. 2019 г. в 20:36, Shane Duan <sduane...@gmail.com>: > I am having similar problem: I am testing with a one-node-cluster.
