Chen Liang commented on HDFS-11530: ----------------------------------- hi [~linyiqun], I've created JIRA HDFS-11535 as a placeholder for the performance test results and any further discussion/suggestions. Also we proposed a way to integrate this new chooseRandom method, by a mixture of both the current and the new methods. Do you mind taking a look at this JIRA? Thanks! > 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 > Components: namenode > Affects Versions: 3.0.0-alpha2 > Reporter: Yiqun Lin > Assignee: Yiqun Lin > Attachments: HDFS-11530.001.patch > > > The work for {{chooseRandomWithStorageType}} has been merged in HDFS-11482. > But this method is contained in new topology {{DFSNetworkTopology}} which is > specified for HDFS.
