>             Project: Hadoop HDFS

> When the NameNode receives the data (FBR) from the DataNode, it will put the 
> data in the queue (BlockReportProcessingThread#queue), and there will be 
> threads processing them thereafter.
> When the DataNode wants to send data (here, FBR) to the NameNode, it will 
> first obtain a blockReportLeaseId from the NameNode. If the DataNode data 
> already exists in the queue, there is no need to assign a blockReportLeaseId 
> to the DataNode again.
