redis_writer.cc:115] [kvrocks2redis] CRITICAL - redis sync return error , administrator confirm needed : -administor permission required to perform the command

Yes, thanks for your feedback. We should use flushdb instead of flushall when flushing the target db.

I'll fix it as soon as possible.

What @git-hulk mentioned is indeed a problem, but I don't think it is the cause of your problem. Can you provide more information (Your kvrocks2redis configuration; Your behavior at the Kvrocks) @xyxu
