Assignee: Alexandr Kuramshin (was: Semen Boikov)
> Node considered as failed can cause failure of others nodes
> -----------------------------------------------------------
>
> Key: IGNITE-6700
> URL: https://issues.apache.org/jira/browse/IGNITE-6700
> Project: Ignite
> Issue Type: Bug
> Security Level: Public(Viewable by anyone)
> Components: general
> Reporter: Semen Boikov
> Assignee: Alexandr Kuramshin
> Priority: Critical
>
> Node considered as failed can cause failure of others nodes in cluster.
> There is an issue in TcpDiscoveryAbstractMessage.failedNodes processing, if
> message is received from node considered as failed, then failedNodes should
> be ignored.
> Possible scenario:
> - there are 4 nodes (1 -> 2 -> 3 -> 4)
> - node 3 temporary lost connection with others
> - node 2 considers 3 as failed, node failed event is fired for 3
> - node 3 considers 4 as failed, adds 4 in nodeFailedList, then it restores
> connection with 1 and currently 1 will process nodeFailedList from 3 (even if
> 3 is already considered as failed)
