------------------------------------------
Summary: Validate connection from a pre-previous node
Key: IGNITE-7163
URL: https://issues.apache.org/jira/browse/IGNITE-7163
Project: Ignite
Issue Type: Sub-task
Affects Versions: 2.3
Reporter: Alexandr Kuramshin
Assignee: Alexandr Kuramshin
If some pre-previous node connects to the local node with the previous node in
the message's failed nodes collection additional steps should be done:
# Connection with the previous node should be validated.
# If a message from the previous node was not received a long time ago, the
previous node should be considered as failed and the pre-previous node
connection accepted.
# If the previous node connection is alive then different scenarios possible
## Answer with a new result code causing the pre-previous node to try to
reconnect to the previous node
## Break connection with the pre-previous node causing to continue the possible
cluster split.
## Check connections with nodes after pre-previous node and delay decision by
answering RES_WAIT to get more predictable split and stable topology.
