    [ https://issues.apache.org/jira/browse/HADOOP-1185?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12488430 ] 

dhruba borthakur commented on HADOOP-1185:
------------------------------------------

The apache common logging API does not let me set logging levels. Can somebody please suggest how I can get to the underlying log4j object?

> I would like to switch on the debug log level of the namenode without restarting it. This is needed to analyze a production system.
> Can somebody please advice on how to set the loglevel dyncamically on a running namenode? I was thinking of enhancing dfsadmin to make an RPC to the namenode to set a specified logging level. But the apache common logging APi does not export an API to change logging levels.
