[jira] [Created] (HDFS-11530) Use HDFS specific network topology to choose datanode in BlockPlacementPolicyDefault

Yiqun Lin created HDFS-11530:
--------------------------------

             Summary: Use HDFS specific network topology to choose datanode in BlockPlacementPolicyDefault
                 Key: HDFS-11530
                 URL: https://issues.apache.org/jira/browse/HDFS-11530
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: 3.0.0-alpha2
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin


The work for {{chooseRandomWithStorageType}} has been merged in HDFS-11482. But this method is contained in new topology {{DFSNetworkTopology}} which is specified for HDFS. We should update this and let {{BlockPlacementPolicyDefault}} use the new way.
