> Java thin client: throw handshake exception on connect phase
> ------------------------------------------------------------
>
> Key: IGNITE-8097
> URL: https://issues.apache.org/jira/browse/IGNITE-8097
> Project: Ignite
> Issue Type: Task
> Components: thin client
> Reporter: Vladimir Ozerov
> Assignee: Alexey Kukushkin
> Priority: Major
> Fix For: 2.5
>
>
> Currently a call to {{Ignition.startClient}} return client instance even if
> we know for sure that connection is not usable. Real exception (e.g. protocol
> mismatch, auth error, etc.) is thrown on attempt to execute first operation
> on the client. This is bad UX - use may think that everything is OK for a
> long time.
> Instead, connection should be established eagerly in {{startClient}}, any
> exception should be propagated to the user immediately.
