Hello i'm using hadoop 0.20.0 with raid. My architecture is as follows: 192.168.0.1 Namenode and RaidNode 192.168.0.2-5 DataNodes
I would like when i copy from local a file that the RaidNode creates the chunks immediately and then the Namenode will send to the Datanodes blocks and chunks. The hadoop fs with basic configuration willl first sent all blocks to the datanodes and after the Raidnode will ask to have the blocks back to encode it and then transmitting the chunks to the Datanodes. I would like to unify the two steps, is there a way to do that? Thanks in advance Giulio
