             Summary: Raft group reconfiguration on node leave
                 Key: IGNITE-16668
                 URL: https://issues.apache.org/jira/browse/IGNITE-16668
             Project: Ignite
          Issue Type: Improvement
            Reporter: Sergey Chugunov


When a node serving as part of Raft group for a particular partition fails data 
it stores is lost.

So keeping failed node in Raft group configuration is wrong, node should be 
removed from the group.

But reconfiguring the group is tricky and may interfere with rebalancing 
protocol for persistence case. So we need to propose and discuss design for 
group reconfiguration separately.
