[GitHub] [hadoop] zhangshuyan0 commented on pull request #5398: HDFS-16922. The logic of IncrementalBlockReportManager#addRDBI method may cause missing blocks when cluster is busy.

   It's great to make sure dn only report the replica with maximum timestamp. 
   Even though [HDFS-16146](https://issues.apache.org/jira/browse/HDFS-16146) already merged, is it still possible to miss blocks in trunk when the replication factor is 2 ?  Would you mind adding a UT for reproducing this case?
