Yiqun Lin commented on HDFS-11530: ---------------------------------- Thanks [~vagarychen] for the comments. I take some time to looked into this. I picked up one other type test failure {{TestDatanodeRegistration#testChangeIpcPort}} to have a debug. The removing node operation is failed if the node registers to namenode again with different node name. Maybe this test failure leads other test failed. [~vagarychen], could you share your thought of this or we can file a new JIRA to have a track to cover this case? It seems there are still some works we should do before making {{DFSNetworkTopology}} as the default NetworkTopology {{NetworkTopology}}. In addition, I am thinking if we use {{DFSNetworkTopology}} as the default class, is that mean the other subclass of {{NetworkTopology}}(e.g. NetworkTopologyWithNodeGroup) will be not allowed used in HDFS? > 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, HDFS-11530.002.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.
