Subject [jira] [Resolved] (HDFS-870) Topology is permanently cached
Date Wed, 02 Nov 2011 17:53:33 GMT

     [ https://issues.apache.org/jira/browse/HDFS-870?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Allen Wittenauer resolved HDFS-870.

    Resolution: Won't Fix

Sites should implement their own Java class that duplicates the current script method but
implements caching.  Closing as won't fix.

> 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.
