Description
The Present AvailableSpaceBlockPlacementPolicy extends the Default Block Placement policy, which makes it apt for Replicated files. But not very efficient for EC files, which by default use. BlockPlacementPolicyRackFaultTolerant. So propose a to add new BPP having similar optimization as ASBPP where as keeping the spread of Blocks to max racks, i.e as RackFaultTolerantBPP.
This could extend BlockPlacementPolicyRackFaultTolerant, rather than the BlockPlacementPOlicyDefault like ASBPP and keep other logics of optimization same as ASBPP
