Subject [jira] [Created] (HDFS-5254) Reconfigure DN's topology without restart DN
Date Tue, 24 Sep 2013 07:36:03 GMT
Junping Du created HDFS-5254:
--------------------------------

             Summary: Reconfigure DN's topology without restart DN
                 Key: HDFS-5254
                 URL: https://issues.apache.org/jira/browse/HDFS-5254
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Junping Du


In some cases (like: VM live migration in virtualization or SDN in cloud), the DN's network
topology is changed in runtime. We should figure out some way to reconfigure it without stop/start
DN.
