Subject [jira] Created: (HDFS-870) Topology is permanently cached
Date Tue, 05 Jan 2010 23:51:57 GMT
Topology is permanently cached
------------------------------

                 Key: HDFS-870
                 URL: https://issues.apache.org/jira/browse/HDFS-870
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Allen Wittenauer


Replacing the topology script requires a namenode bounce because the NN caches the information
permanently.  It should really either expire it periodically or expire on -refreshNodes.
