Yiqun Lin updated HDFS-13418: ----------------------------- Status: Patch Available (was: Open) > 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 > Priority: Major > Attachments: HDFS-13418.001.patch > > > 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?
