> The issue is that query request was sent on a backup node and by the time request has arrived, the partition was already evicted, which resulted in "Partition cannot be reserved" exception. We should automatically retry if this exception is encountered.
> I believe we have logic that retries, but it looks like there is a bug in that logic.
