             Summary: Add a test for a leader change during full rebalance to a leader with enough log
                 Key: IGNITE-18864
                 URL: https://issues.apache.org/jira/browse/IGNITE-18864
             Project: Ignite
          Issue Type: New Feature
            Reporter: Roman Puchkovskiy
            Assignee: Roman Puchkovskiy
             Fix For: 3.0.0-beta2


What happens if a leader changes during a full rebalance so that the new leader has enough log to avoid a full rebalance (because it can just feed the follower using AppendEntries RPC)?
I expect the full rebalance to be canceled, clear the storages and set the initial (equal to 0) {*}lastAppliedIndex *and *lastAppliedTerm{*}.
And also what index will be sent to the new leader, if during a full rebalancing on the recipient it will be equal to {*}-1{*}.
