Vinay created HDFS-5581:
---------------------------

             Summary: NameNodeFsck should use only one instance of BlockPlacementPolicy
                 Key: HDFS-5581
                 URL: https://issues.apache.org/jira/browse/HDFS-5581
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: namenode
            Reporter: Vinay
            Assignee: Vinay


While going through NameNodeFsck I found that following code creates the new instance of BlockPlacementPolicy for every block.

{code}      // verify block placement policy
      BlockPlacementStatus blockPlacementStatus = 
          BlockPlacementPolicy.getInstance(conf, null, networktopology).
              verifyBlockPlacement(path, lBlk, targetFileReplication);{code}

It would be better to use the namenode's BPP itself instead of creating a new one.
