Subject Data block placement in HDFS
Date Tue, 03 Jul 2012 18:41:08 GMT

It's interesting to see HDFS provided an interface BlockPlacementPolicy for
users to define their own data placement policy in Hadoop v0.21, v0.22, and
I think it's very useful for some applications. However, I can't find this
interface in the latest stable version of Hadoop v1.0. Is the interface
replaced by something else or abandoned completely? If it's abandoned,
could anyone tell me why?
