------------------------------------------
Summary: Cluster falls apart on topology change when DNS service
is unavailable
Key: IGNITE-21630
URL: https://issues.apache.org/jira/browse/IGNITE-21630
Project: Ignite
Issue Type: Bug
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
Requests to DNS service performed synchroniously by some critical discovery
threads. Timeout for such requests can't be controlled by java code (see
[https://bugs.openjdk.org/browse/JDK-6450279]). This leads to segmentation of
nodes and falling apart cluster.
For example, stack of {{tcp-disco-msg-worker}} thread with request to DNS
service:
