> Good improvement. Not think carefully but my first feeling, IBR - FBR mis-order could trigger some issues, such as miss some block report? One case, a. generate full block report, b. received one replica named `r` and send IBR, c. send full block report; And NameNode process FBF and IBR as the above order, then NameNode will consider that this DataNode does not include replica `r`, right? > > Thanks. In the NamenodeRpcServer sideļ¼the ibr and fbr will both into BlockManager.BlockReportProcessingThread queue . I think the order of ibr and fbr cannot guarantee in the previous hadoop version.  blockreport will be processed with one after one. But the ibrs order is not guaranteed. -- This is an automated message from the Apache Git Service.
