Assignee: (was: Vladimir Ozerov)
> Coordinator floods network with partitions' full map messages
> -------------------------------------------------------------
>
> Key: IGNITE-2801
> URL: https://issues.apache.org/jira/browse/IGNITE-2801
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.5.0.final
> Reporter: Denis Magda
> Priority: Critical
> Labels: community, important
> Fix For: 1.6
>
> Attachments: basic_node.nps, basic_node.png, coordinator.nps,
> coordinator.png
>
>
> It is detected that the more machines in the cluster we have and the more
> caches are started then the more outgoing traffic is produced by a
> coordinator node.
> As an example in the current deployment
> - 30 nodes;
> - 67 caches;
> - caches are empty and the cluster is not used at all (idle).
> the coordinator constantly uses 300 Mbit/s of outgoing traffic. In contrast
> each other node shows constant 10 Mbit/s usage of incoming traffic.
> Most likely the reason is that the coordinator indefinitely sends partitions
> full map for all the caches to all the nodes. This shouldn't happen.
> Need to debug the reason of the issue and fix it.
> Attached snapshots taken from the coordinator and on of cluster's nodes.
> Probably they would help.
