Hi,

I have an = input which I divided into 256 blocks into hdfs, each of 10 MB.

My = question is: How can I download some of these blocks only ? I tried from th= e Web UI  and look at "Advanced view/download options" where all the i= nput blocks are listed. However, when I try to specify "Chunk size to view = (in bytes, up to file's DFS block size):" I got an error like: "Invalid inp= ut (genstamp absent)"

Do you know other way to copy the content of s= ome blocks ? I am using Hadoop 1.0.3

Thanks,
Robert
