> 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.
