---------------------------------------
Summary: Java thin: client init hangs when cluster discovery is
enabled and returned addresses are not reachable
Key: IGNITE-22964
URL: https://issues.apache.org/jira/browse/IGNITE-22964
Project: Ignite
Issue Type: Improvement
Components: thin client
Reporter: Pavel Tupitsyn
Assignee: Pavel Tupitsyn
Fix For: 2.17
Initial *ReliableChannel#channelsInit* call synchronously calls
*discoveryCtx::refresh*, causing the client initialization to hang on
unreachable addresses
* *discoveryCtx::refresh* must be run only in background threads
* Client initialization should finish as soon as a connection is established to
one of the configured addresses
*channelsCnt.get() == 0* check does not work properly:
