[jira] Created: (HDFS-870) Topology is permanently cached
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.
