>             Project: Ignite
>          Issue Type: Task
>          Components: cache
>            Reporter: Andrew Mashenkov
>            Assignee: Vitaliy Biryukov
>            Priority: Critical
>             Fix For: 2.8
> Assume, we have event listener that detects partition loss events and apply some actions
to recover lost data.
> After recovery process finished an Ignite.resetLostPartitions() method should be called
to mark all lost cache partitions as healthy.
> It is possible Ignite.resetLostPartitions() will be called during exchange, but right
before a new partition loss event will be fired.
> E.g. exchange thread own GridDhtPartitionTopologyImpl write lock in detectLostPartitions()
method, while user thread will wait for the lock inside Ignite.resetLostPartitions().
> So, after a new partition loss will be detected, is will be not possible to abort user
action and state of just lost partition will be reset.
> For that case, we should either abort resetLostPartitions() or reset partitions state
regarding topology version provided by user some how.
