That means when we have new block placement > policy, we need to modify BlockManager to account for the new policy. Ideally > BlockManager should ask BlockPlacementPolicy object instead. That will allow > us to provide new BlockPlacementPolicy without changing BlockManager. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
