Subject DFS. How to read from a specific datanode
Date Wed, 06 Aug 2008 01:59:55 GMT

This is about dfs only, not to consider mapreduce. It may sound like a
strange need, but sometimes I want to read a block from a specific
data node which holds a replica. Figuring out which datanodes have the
block is easy. But is there an easy way to specify which datanode I
want to load from?
