      Description

      Currently in each choosing round of BlockPlacementPolicy#chooseTarget (e.g., round 1 for choosing local storage, round 2 for remote rack, etc.), we only take into account the first storage type in the storage type list. This may
      fail to choose the local machine or sometimes may even fail to choose enough nodes.
