---------------------------------------
Summary: 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
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.
