Thanks a lot. I will take a look on the balancer and decommissioning code.

The balancer does something similar. It uses
DataTransferProtocol.replaceBlock.

You can get info about all blocks stored in perticuler data node, i,e block
report. But you to handle, move in block level not in file or start and end
bytes level.

Haven't looked at the source but the thing you are trying to do sounds
similar to what happens when you are decommissioning a datanode. I would
hunt for that code.

Hi Chris,
Actually I need this functionality for my research, basically for fault
tolerance. I can calculate some failure probability for some data nodes
after certain unit of time. So I need to copy all the blocks reside on
these nodes to another nodes.
Thanks

Can you outline why one would want to do that? The blocks are disposable so
it is strange to manipulate them directly.

Hi All,
How can copy a certain hdfs block (given the file name, start and end
bytes) from one node to another node ?
Thanks
