Anton Vinogradov updated IGNITE-18332:
--------------------------------------
Description:
{{GridDhtPartitionsExchangeFuture#finalizePartitionCounters}} is used to close
the gaps at partition counters after the craches (automatically).
Even at the PME-free switch (when backup must become primary asap) it is not
correct to loose the counters data (gaps).
At PME-free switch, due to tx recovery, it's expected to have same gaps on
backups, but primary may have some gaps committed.
Closing the gaps also maks backups's operations as committed.
And we'll gain inconsistent state ot ex-primary join ?(since rebalance will see
no gaps on backups).
Gaps must be closed only ecxplicitly using the consistency repair utility.

{{GridDhtPartitionsExchangeFuture#finalizePartitionCounters}} is used to hide
gaps at partition counters after the craches.
Even at the PME-free switch (when backup must become primary asap) it is not
correct to loose the counters data (gaps).
Main problem here is that "different gaps" means "different content" and
calling {{finalizePartitionCounters()}} we mark different content as the same.
