> 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.
