Dmitry, Not yet, it looks like architectural issue. Ignite provide a error prone method for resetLostPartition state in public API.
However, IGNITE-5302 is about issue during node startup. I'd think we can use some internals (e.g. topology version) to workaround this. If you are sure IGNITE-5302 will solve 7832 then you may close as a duplicate. If IGNITE-5302 can be fixed with using some workaround, e.g. checking topology version when reset partition state, then let's keep 7832 open.
