> Another node fails with failure of target node.

> 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: 1h 40m
> Remaining Estimate: 0h
>
> The discovery ducktape test [1] has detected unexpected failure of another
> node.
> Scenario:
> The nodes have relative places in the ring: N 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. The mentioned timeouts have been turned relative. The
> timeout of backward connection check is now generally shorter than the
> timeout to recover connection.
