> Fix middle node failed when failed next node and previous.
> ----------------------------------------------------------

> Key: IGNITE-13705
> URL: https://issues.apache.org/jira/browse/IGNITE-13705
> Project: Ignite
> Issue Type: Bug
> Reporter: Vladimir Steshin
> Assignee: Vladimir Steshin
> Priority: Major
> Time Spent: 50m
> Remaining Estimate: 0h
>
> The discovery ducktape test [1] has detected failure of third node in the
> middle of 2 simulateously failed nodes.
> Scenario:
> Two nodes fail at the same time. The nodes have relative places in the ring:
> N-1 and N+1.
> Node N detects failure of node N+1. Node N tries to connect to node N+2. Node
> N+2 checks backward connection to node N+1.
> Problem:
> Node N can fail too.
> Cause:
> The timeout on node N to recover connection to node N+2 appears shorter than
> timeout on node N+2 to check connection to N+1.
> Fix:
> Introduced a fundamental timeout value to check/recover connection based on
> current configuration. Not a constant. Mentioned above timeouts have been
> made relative. The timeout of backward connection check is now generally
> shorter than the timeout to recover connection.
