Hey Jason, There are some non-public APIs to do this -- have a look at how the Balancer works - the dispatch() function is the guts you're looking for. It might be nice to expose this functionality as a "limited private evolving" API.
In general, though, keep in mind that, whenever you write data, you'll get a local copy first, if the writer is in the cluster. That's how HBase gets locality for most of its accesses. -Todd On Thu, May 26, 2011 at 11:36 AM, Jason Rutherglen <jason.rutherg...@gmail.com> wrote: > Is there a way to send a request to the name node to replicate > block(s) to a specific DataNode?
