      Now there will be strange a warn log

      2019-05-30 14:59:38,426 WARN  [RS:1;zhangduo-ubuntu:39885.replicationSource.wal-reader.zhangduo-ubuntu%2C39885%2C1559199556433,2] wal.ProtobufLogReader(422): Encountered a malformed edit, seeking back to last good position in file, from 2459 to 2459

      And in TestReplicationStatus* UTs, we set the retry interval to 100ms, so the logs are flooded with these useless warns...
