> This is actually the reason for HDFS-734 (TestDatanodeBlockScanner timing out). The issue
is that DFSInputStream relies on readChunk being called one last time at the end of the file
in order to receive the lastPacketInBlock=true packet from the DN. However, DFSInputStream.read
checks pos < getFileLength() before issuing the read. Thus gotEOS never shifts to true
and checksumOk() is never called.
