Vladimir Ozerov updated IGNITE-5457:
------------------------------------
Fix Version/s: (was: 2.3)
> Weird discovery behavior on split brain.
> ----------------------------------------
>
> Key: IGNITE-5457
> URL: https://issues.apache.org/jira/browse/IGNITE-5457
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 2.0
> Reporter: Alexei Scherbakov
> Priority: Critical
>
> I observe buggy behavior in case of simulated split brain.
> Nodes in DataCenter1 (where coordinator is located) are slowly leave grid,
> while nodes in DataCenter2 stay in grid forever.
> In logs I see multiple attemps to kick coordinator by communcation by connect
> timeout, but number of nodes does not change.
> Note what my failureDetectionTimeout is significantly higher than
> communication connect timeout.
> Looks like coordinator cannot be kicked from topology by TcpCommuncationSpi.
