Aleksey Plekhanov updated IGNITE-9494:
--------------------------------------
Fix Version/s: (was: 2.9)
> Communication error resolver may be invoked when topology is under construction
> -------------------------------------------------------------------------------
>
> Key: IGNITE-9494
> URL: https://issues.apache.org/jira/browse/IGNITE-9494
> Project: Ignite
> Issue Type: Bug
> Components: cache, zookeeper
> Affects Versions: 2.5
> Reporter: Pavel Kovalenko
> Priority: Major
>
> Zookeeper Discovery.
> During massive node start and join to topology there can happen communication error problems which can lead to invoking communication error resolver.
> Communication error resolver initiates a peer-to-peer ping process on all alive nodes. Youngest nodes in a cluster may have the not complete picture about alive nodes in a cluster. This can lead to a situation, that youngest node will not ping all available nodes, and the coordinator may decide that those nodes have an unstable network and unexpectedly kill them.
> We should throttle communication error resolver in case of massive node join and give them a time to get the complete picture about topology.
