             Summary: Full rebalance testing extension
                 Key: IGNITE-18433
                 URL: https://issues.apache.org/jira/browse/IGNITE-18433
             Project: Ignite
          Issue Type: Task
            Reporter: Kirill Tkalenko
             Fix For: 3.0.0-beta2


Scenarios for testing: (current vaults: *TxStateStorage* and *MvPartitionStorage*)
* During a full rebalance, the leader changes, what will happen?
I expect the current rebalance to be canceled and a new one to start with empty storages and set 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*.
* What happens if a leader changes during a full rebalance that has enough log to avoid a full rebalance?
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*.
* Suppose a full rebalancing for one of the storages ended successfully, and it has updated (not equal to -1) *lastAppliedIndex *and *lastAppliedTerm*, while for the other we did not have time to complete the full rebalancing and the node fell. 
What will happen to both storages after the node is powered on?
I expect both stores to be cleared and have initial (equal to 0) *lastAppliedIndex *and *lastAppliedTerm*.

Each scenario can be tested in a separate ticket
