> Bug introduced by HADOOP-2758. This part is removed in HADOOP-1702, but 1702 is not yet
ready. I will submit a patch. 
> The first datanode in the pipeline receives data with non-interleaving checksum and sends
interleaving checksum to mirror (this mismatch is temporary till HADOOP-1702). The packet
size differs in these two cases and DataNode did not correct the packet size in the header.
