> Key: IGNITE-7832
> URL: https://issues.apache.org/jira/browse/IGNITE-7832
> 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.
