Subject The mechanism of choosing target datanodes
Date Thu, 23 Apr 2009 09:14:37 GMT

If a cluster has many datanodes and I want to copy a large file into DFS. 
If the replication number is set to 1, does the namenode will put the file
data on one datanode or several nodes? I wonder if the file will be split
into blocks then different unique blocks are on different datanodes.
