[jira] [Created] (IGNITE-8097) Java thin client: throw handshake
exception on connect phase
Vladimir Ozerov created IGNITE-8097:
---------------------------------------
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.
