Chris Li created HADOOP-10811: --------------------------------- Summary: Allow classes to be reloaded at runtime Key: HADOOP-10811 URL: https://issues.apache.org/jira/browse/HADOOP-10811 Project: Hadoop Common Issue Type: New Feature Components: conf Affects Versions: 3.0.0 Reporter: Chris Li Assignee: Chris Li Priority: Minor
Currently hadoop loads its classes and caches them in the Configuration class. Even if the user swaps a class's jar at runtime, hadoop will continue to use the cached classes when using reflection to instantiate objects. This limits the usefulness of things like HADOOP-10285, because the admin would need to restart each time they wanted to change their queue class. This patch is to add a way to refresh the class cache, by creating a new refresh handler to do so (using HADOOP-10376) -- This message was sent by Atlassian JIRA (v6.2#6252)
