Harsh J commented on HDFS-1451:
-------------------------------

Different policy per namespace would solve the same need, and also keep the 
metadata separate, no?
                
> Extend the pluggable block placement policy interface to handle/allow 
> file-level intelligence

> The current pluggable block placement policy interface 
> (https://issues.apache.org/jira/browse/HDFS-385) sets the policy globally. I 
> propose to have this interface be extended to allow setting the policy on a 
> file-level basis. For example, there may be cases where certain files may 
> simply need the default policy and certain other files need more complex 
> block placement policies.
