dynamically change dfs log levels

                 Key: HADOOP-1185
                 URL: https://issues.apache.org/jira/browse/HADOOP-1185
             Project: Hadoop
          Issue Type: Improvement
          Components: dfs
            Reporter: dhruba borthakur
         Assigned To: dhruba borthakur

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.
