Description

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.
