---------------------------------------
Hi [~xtern],
I think that GridDhtPartitionTopologyImpl.resetLostPartitions(...) shouldn't be
called on non-coordinator nodes at all. They should simply send their local
partition states and counters, just as on every other PME type. It is
coordinator's job to change those states after it receives all single messages.
> resetLostPartitions() leaves an additional copy of a partition in the cluster

>
> If there are several copies of a LOST partition, resetLostPartitions() will
> leave all of them in the cluster as OWNING.
> Scenario:
> 1) Start 4 nodes, a cache with backups=0 and READ_WRITE_SAFE, fill the cache
> 2) Stop one node - some partitions are recreated on the remaining nodes as
> LOST
> 3) Start one node - the LOST partitions are being rebalanced to the new node
> from the existing ones
> 4) Wait for rebalance to complete
> 5) Call resetLostPartitions()
> After that the partitions that were LOST become OWNING on all nodes that had
> them. Eviction of these partitions doesn't start.
> Need to correctly evict additional copies of LOST partitions either after
> rebalance on step 4 or after resetLostPartitions() call on step 5.
> Current resetLostPartitions() implementation does call checkEvictions(), but
> the ready affinity assignment contains several nodes per partition for some
> reason.
