Tao Jie created HDFS-13418: ------------------------------ Summary: NetworkTopology should be configurable when enable DFSNetworkTopology Key: HDFS-13418 URL: https://issues.apache.org/jira/browse/HDFS-13418 Project: Hadoop HDFS Issue Type: Improvement Affects Versions: 3.0.1 Reporter: Tao Jie Assignee: Tao Jie
In HDFS-11530 we introduce DFSNetworkTopology and in HDFS-11998 we set DFSNetworkTopology as the default implementation. We still have {{net.topology.impl=org.apache.hadoop.net.NetworkTopology}} in core-site.default. Actually this property does not effect once {{dfs.use.dfs.network.topology}} is true. in {{DatanodeManager}},networkTopology is initialized as {code} if (useDfsNetworkTopology) { networktopology = DFSNetworkTopology.getInstance(conf); } else { networktopology = NetworkTopology.getInstance(conf); } {code} I think we should still make the NetworkTopology configurable rather than hard code the implementation since we may need another NetworkTopology impl. I am not sure if there is other consideration. Any thought?
