-----------------------------------
Summary: 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
Assignee: Vladimir Ozerov
Priority: Critical
Fix For: 1.6
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.
