> Thank you very much for your detailed description of the bug, it made me understand. We need to fix the case where there are two internal blocks of the same block group on the same DN. But I think it's not a good idea to do it in DirectoryScanner. How does datanode know if there are two duplicated block group? Maybe they are just two different replication blocks with the same first 60 digits of the blockID. Thanks @zhangshuyan0 for your replying. I think we can use `BlockIdManager.isStripedBlockID` and `BlockIdManager.convertToStripedID` to judge the two blocks are EC blocks and they have same block group. -- This is an automated message from the Apache Git Service.
