>             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.
